Fulltone OCD

Pretty simple to get a usable sound out of this pedal. Getting a better sound just takes some user time. I don't find the toggle switch very useful as a live option because of the volume difference.

To my ear seems a little to have a little more "air" and is pretty well sensitive to pick dynamics. The harmonics and overtones are nice. Not sure it lives up to Fulltone's claims but none the less very nice.

Looks like it will be reliable.

Sent Mike at Fulltone an email regarding my Fulldrive 2 and converting it to his bass version. He emailed back stating the two components that would have to be changed and a photo pointing them out.

Blues, blues rock, and that genre. Playing since 1976. Mesa Boogie Subway Blues and MB 12" extension cabinet and several Analog Man modded Boss Distortion/Overdrive pedals and an old Ibanez chorus. G&L ASAT Classic. The pedal matches nicely with the G&L.

Simple to use, although it would be helpful if the target amp / setup that this was made for was included with knob settings ... but maybe that is asking too much?

Sounds very good, not the best OD on the market, but a pretty good all arounder if you play a variety of styles ... it works best with a Marshall type just barely breaking up. I do not like the sound of it on any setting with a Fender Super or Twin. For a $179 pedal, it is average in its class, which is not a bad thing. I think better tones are coming from othe boutique pedal makers like Menatone and Keeley, but this sure beats any stock Boss overdrive.

Fulltone stuff is extremely reliable. In the 10 years or so I have used Mike Fuller's products (12 or so pedals) I have only had a few problems with switches, and he has since replaced the old style switches.

Hopefully you will never have to deal with Fuller. Compared to Robert Keeley or Brian Mena or any of the other boutique pedal guys, Mike Fuller is very trite and not in it for the customer. The good news is his stuff is very reliable.

Solid pedal, and a price drop down to $159 make this a great buy right now. If you crave better tones and need a pedal that covers a lot of bases, get this one. It is a great place to start if you are trying to find your sound.

I have version 3.0, manufactured in April 2007.

This pedal is extremely easy to use. Volume, Gain and Tone knobs, that's it. There are two modes that can be selected with a toggle switch: HP & LP. HP sounds more British, very much like a vintage Marshall Plexi. LP is more of an American Overdrive, like a cranked up Fender. I personally like the HP mode more, but they are both great. The HP seems to be slightly louder, but I think that's because it accents the higher frequencies.

The only thing I would caution anybody with this pedal is that the volume control is very touchy. There's a lot of headroom and it can get away from you really quickly. I leave my volume setting around 9 o'clock, and my gain and tone are both at 12:00 o'clock. This seems to be a pretty good setup for me so far, but I've got plenty of room to adjust as necessary.

In short, this pedal sounds GREAT!

I play various Strats (single-coils & humbuckers) into a Koch Multitone 2x12 Combo. The only effects I use are (in order) a Budda Wah, a Fulltone Mini Deja Vibe, the Fulltone OCD Overdrive and then amp. I use a TC G-Major rack processor in the parallel effects loop of the Koch for some subtle delay, but that's it.

I have been playing for 30 years. I have had this pedal for about two months, so I've had time to get used to it. I bought this pedal to give my amp channels a little push over the edge and that's what it does perfectly.

I have posted several sound samples on my web site and you can hear eveything in action (www.mjriley.com)

This pedal is built the way pedals should be built...solid! I've got it mounted on a pedalboard with velcro, but it comes with some nice clear silicone no slip-feet which are a real nice added touch.

The knobs and pots are all heavy duty. I like the fact that the knobs are somewhat 'stiff' and don't flop around when you come into contact with them.

Very solidly built. Great design.

Haven't had to deal with them, don't expect to.

This is a great pedal. I've tried and owned several other overdrive pedals and this one has proven to be the best. It's really brought out the best of my amp and tone. It allows me to get huge tones and feedback at a lower level without shattering my eardrums or windows.

I would recommend this pedal to anyone looking for a good clean overdrive with plenty of volume and gain to spread around.

Nice job, Mr. Fuller!!!

Very easy to use. There's a one page instruction sheet aht comes with the OCD. But, just plug it in and let your ears do the work. Very simple my 11 year old son uses it!!

Awesome tones! I don't know what "ItDoesn'tMatter's" gripes are about. It's obvious he's very disgruntled or jealous with Mike Fuller's company..

Aside for that, the OCD does everything I'm looking for in sound. No altered or muddy tones. I'm personally not into pedals or pedal boards to try to emulate an artist or group. So the sound I'm looking for comes from my amp and guitar. I too have an "expensive amp" and strive for a certain sound. The OCD doesn't alter that sound in any way especially when playing slide guitar.

Do yourself a favor and test drive the OCD if you're serious. You won't be disappointed. Let your ears decide for you.

Very strong construction. The pots that are used in the OCD are pots used on high end amps. They're not cheap pots.

Hasn't needed repairing.

I don't issue "10" on products. In my opinion, this box deserves a 12.

The features have all been listed, ad nauseum. Being a user of highend tube amps, (the $2k and over stuff) the OCD is no where close to the tone of quality tube overdrive, saturation, etc. (Preamp or power amp section).

The OCD's main and worst function is that it is great boost pedal, if you like an unusable level of boost that won't be tolerated by band mates or in a live setting.

I gave this a rating of 3 based on the sweep of the volume only being usable below 9 o'clock. (The rise after that is obscene). The tone knob is the most usable feature but the drive is less than stellar after the 12 o'clock position and uneeded below. More tone sucking than enghancing actually. The LP/HP mini-toggle is best discribed as "less mud, more mud".

The actual footswitch is the type that gives a "pop" when ingaged or disingaged and with today's technology, even in analog pedals, there is no need to use this type of component, by-pass or otherwise. This feature alone makes this pedal unusable for recording if the need to switch is required during live tracking.

The box looks cool, if that is your thing.

It doesn't sound anything like Brittish amps of any kind, vintage tones or some other overused industry phrase and it detracts from quality tube tone-saturation. Please keep in mind that my criticism is not from the so called honeymoon period one way or the other.

I have had the pedal for awhile and have tried to like it and yes I have tried moving in every position of the chain or alone, and with 7 different amps and I still don't like it. I also don't hate it, I just didn't hear the results from it that were so hyped in the first place. I use power conditioners, Mogami, George L's, etc. so it's not the cables either.

I'm actually quite pissed because I want to like it based on Fulltone's web presentation and the general internet buzz. I should know better by now, especially having an arsenal of great amps and instruments at my disposal.

Pedal's of any level, especially overdrive, distortion, etc. become more of a liabiliy at some point but I was hopefull that the OCD would be an ehancement. It wasn't and isn't, and even ain't and it should've.

In addition, I did try it on an old but excellent Westbury amp (the only solid state amp I own) which has a early plexi tone for recording and the OCD was slighly usefull in that application. Again however, the tone knob was the primary effect being utilized on the OCD. (I don't use EQ pedals because I don't need to anymore). The OCD seems to be an overpriced, one knob EQ pedal so maybe that's what your looking for. There are better boost pedals but that's not why I purchased the OCD.

I rated this a 4 because the tone knob is useable for tone shaping, but isn't that what EQ is for ?

The quality housing/case of this and many other pedals now on the market far exceed anything from the past. The OCD appears to be well made from a construction standpoint. However, a pretty face sure don't make no pretty heart.

If I don't like it, I won't use it, so in that case it should last a very long time, especially as a rarely used EQ pedal.

In an e-mail to Mikehole Fuller, in search of his advice, his reply was absolutely one of the most UNPROFFESIONAL replies from any manufacturer, ever, and I have been purchasing high end equipment for more years than I care to admit.

I was warned in advance that if he replies at all, he would be a total arse and not helpful, so in that regard, he succeeded. Why bother at all? His egotistical, nasty and negative customer service reputation preceeded him and was consequently, confirmed.

In total positive contrast, guys like Bob Sweet (Mojo Vibe) and others like Bob Weil, Roger Mayer (among many) reply within a day or two and make the effort to be helpful to THEIR CUSTOMERS.

Obviously Mikehole Fuller does not need anymore business and there are other and better manufactures (small and large) now available to musicians who create pedals that now exceed Fulltone's. Don't be lazy and follow the crowd or the hype. Do your homework and link in with manufactures that WANT your business and will work to EARN your loyalty.

We all must choose between being informed comsumers or prostitutes for the economy. You decide for yourself.

Lastly, I like Robin Trower, among many other artists who use this or that pedal, but Mr. Trower (or any developed artist) sound's like themself no matter what equipment they uses. Wake up !

If I could rate Fulltone's customer service any lower, I would.

The box looks cool, if that is your thing, but I already said that.

use this pedal as a boost--the overdrive is great, but this thing will add those harmonics that may be missing & give your amp overtones you may have thought weren't there

no noise. i use lp's & soapbars. the ocd can add some brightness as you desire. it really can juice your tone. it's the overtones you need to listen for. let your amp do most of the coloring--then add the ocd's harmonics until you find your color. you could make a 6L6 amp sound like an EL84 sound if you want. you may not want to use it with an amp that's already bright. but the tone control can take the highs & bring them down if you need. i like this pedal with a fender sound, & from what i know mike fuller has those older fenders, so when he makes a pedal, he's making it for his sound. it works good with a boogie lonestar too, which again in a way comes from a fender background

no problems or worries. i have 2--they are a bit different because they are about 2 years apart. no 2 things are ever really alike. one is a bit darker, which can work with a brighter amp. i like them both, & this can help with the room you're playing in--you know how that can be. when you try one out, listen for these qualities--& try different amps to get a feel for the colors

i haven't needed to contact fulltone. the ocd has worked fine from the start. i have had them both for about 2 years

i have been plying for 25 years. i would by it again if needed. the ocd is more of the flavor i've always looked for in an overdrive pedal. you could leave it on all night if you use it as a boost. the fulltone fat boost is a good pedal, but the ocd gives me the harmonics i like.

V3
This thing has great sounds right out of the box and on all settings. It had an HP (think Brit) and an LP (American)and both sound equally fantastic.

I lost the manual at Church (this is where I play w/ the praise band) because I was in such a hurry to try it out. I didn't even miss the manual it was so simple. I do wish I had kept the sticker - I am pretty proud to own this thing.

I play through a tuner-H2O Chorus/Delay - Digitech EX7 - Fulltone - BBE Sonic Stomp - EB volume - Marshal DSL401. My main guitar is an Epi-Dot(2002) or my Fender Am Deluxe Strat (1999).

I was amazed at the boost this thing gives you. I keep the volume at 9 o'clock and Drive at 10. However, I played around with the drive all the way down and the boost up at 2 o'clok and this thing really adds alot of tone to the sound.

It didn't add any noise to my setup and has a true bypass. When on, it still is deathly quiet. The best thing about this pedal is that it reacts to your pick attack fantastically. WOW!!

so far so good.

I play alot of different styles. This won't give you a rectifier sound, but that is not what I desire. If you want a great sounding OD with a very usable pallet of sounds, this is for you.

I have had Digitech tone Driver (tone killer), Boss GT-5 multiple, Behringer V-Amp - and a Digitech RP-7 and all moels and ODs I have used pail in comparison. This is my OD pedal - period.

Having been a long time fan and infatuated with the heavy tones and sonic variants Robin Trower has contributed. I started becoming interested in Fulltone after seeing Robin's new effect line is all Fulltone. After playing some 30 years I have never been happy with stock distortions and a lot of pedals and I have used and played a lot of them over the years from ultra vintage Univibe to modern modeler units. Fulltone is the best. After deciding to move to this line I opted for the OCD as Robin stated it was the best he had heard. The Distortion Pro and Soul Bender are much more intense he uses for dramatic effect on some lines.

The OCD is self explanatory and the sheet manual offers recommended twists for various purposes. Fuller is a genius, period. Finally a player who knows what mods and design sound better!

Basically plug the pedal in and start adjusting. I recommend your best clean channel tone and go from there. Bad sounds do not come out of this box. I am supposed to have the new version 3 model but I have not got a clue on how to make sure this is certain other than trusting Humbucker who I ordered it from. UPS 2 day air and it was here. Marvelous.

I just got a new amp the Carvin V3, with vintage cabinet and it is truly an underestimated amp. Marvelous tones I am getting. I am using my Carvin DC400 which has split coil switches and an active clean boost preamp when desired. Playing this unit through my chain which is at present Amp front DC400 Carvin, DOD Extreme Envelope Follower, Vai Bad Horse Wah, OCD into Carvin V3 head and Carvin 4x12 vintage cab. Loop 1 is running at present my reissue Univibe and Boss DDL (not so happy with either right now hope to replace with Fulltone units). Loop 2 on the amp I have set up as a clean boost using the loops volume adjust this makes the V3 sound incredible.

At once on the LP setting this box sounded most promising with gain around 9 and tone around 10 to smooth it out. I gave just wait I was wanting to hear, the dynamic response distortion boxes just don't have. Fuller recommends running a higher voltage than 9 if you can to make the pedal headroom come out more. I am using a 12v supply Radio Shack model as it seems you can't find the older adjustable voltage ones anymore. 12 was as high as I could get. The immediate sound of this unit was impressive it is dynamic to signal input and cleans up and distorts with signal level. In the case of my beautiful DC400 I use the split coil at neck which gives me a nice strat tone I kick on the on-board pre-amp when I want clean boost from the guitar.

Works so well with the OCD unit I was amazed. My wah also sounded great with the unit and I also found my envelope follower sounds great and even in combination with the wah worked very well. Articulate and pure tone. I am also playing detuned as Robin does a full step down might add to my over all better tone as well. Those who complain about the V3 should try this. I was always a dropped D or on 440 guy and when I tried this I just loved how much easier it was to play. The OCD apparently likes it. Running a higher voltage at 12 is also adding to the pedals dynamic. It can take 18 but I am not into batteries and chaining them.

Its all about opinion kids and as everyone knows everyone has one. Having played for many years from the heaviest blues to the hardest metal I know what I like in tone. This pedal I think sounds best for me in the LP mode as booster but it always just makes the tone come alive just what I was looking for. I get tube saturation gain more than most amps can do with the V3. I used to love my Marshall JCM 2000 but his amp is better and does so much more.

The OCD HP mode cranks up the units distortion for the higher gain crowd. I am not so fond of pedal distortion, I mean how long do you need to play before your gain is no longer tone by over the top saturation for bad playing?

This unit on clean channel makes great gain tones by adjusting the knobs. It sounds better than anything else I have tried to use, more musical and articulate.

I can use the LP mode on my high gain channels and it does not mush out my sound but rather helps the distortion have more life and tonal quality. Everything is dependent upon amp. speakers and guitar and you can't expect a pedal to solve your shit tone problems but truly the OCD is going to help you a lot. I think it is the best pedal I have ever had and I cannot wait to try and get more of the line. I wish he would get his hands on an old Mutron III and develop his version, that would be heaven.

The OCD has incredible volume output, Fuller states it is 30db. I have two clean amp boosts and my guitar pre-amp so I have incredible ability to adjust my sound. If you're a new player I can see how you might like the Metal Zone of something like that, you can mod those pretty good. But after you play a number of years one looks for tone more than just gain. How much gain do you need. Tone is the thing and the OCD brings that to the table. Obsessive Compulsive Drive by the way is the name. I love it, could not be happier. I cannot imagine how anyone could get bad sound out

Fuller makes very high quality high end gear. The best components switches (true bypass) even his battery gets shut off when using the phantom power. The knobs are delightfully hard to turn and have that nice quality feel to them. Super heavy box, doesn't get any better. I have had effects for years I cannot see why this one will not last probably longer.

I have not talked to them but I would really like to put the idea in Mike's head to create a new Mutron III envelope unit he would make it amazing I am sure. I have read everything from the web site and have not called them. Its a small company and they are busy as hell I would imagine. Fulltone is the best, I cannot see how much of anything else really can compete with them. Open them up and check out the way its built and the components.

I cannot rate this catagory because I have had no reason to contact them.

As I said above I have been playing about 30 years or more and I know what sounds good. The OCD stays on all the time in my line I cannot say that of anything. It made my already amazing amp sound better and gave me the beautiful strat tones I was looking for in that Daydream Univibe land. It distorts very well but very musically just by touch and guitar boost. I do not use it for the HP higher gain issues but it does that better than other pedals I have. Those complaining it sounds to digital or stiff need to twist around some more roll the highs off and such. I love it I did not find any bad tones and it can distort like the best amp tone I have ever heard. Fuller made this box after the idea of the smaller amps that have great tone like Jimmy's recording setups and such. I found it to be able to produce an intense musical gain distortion I like better than the other ones I have and heard. I like it for the LP tone enhancement quality but it can gain up on HP as much as anyone should need. I mean really is it playing or just hitting the guitar with your violin? I find the HP gain sounds great when you roll off the highs a little, very smooth to fizz if you want it. I like a heavy low end distortion with articulation of notes on the high end. The OCD is a welcome addition and has sold me on the line in general. I paid $180 for it and its worth it. Buy it do yourself a favor and for god sake twist some knobs and try some new settings, experiment. If you get bad sound out of this I suggest a major overall especially speakers. And really look into Carvin their guitars and amps are great I have been using them for years. The Marshall is gone but the V3 rules the hill.

Pretty simple, all knobs are self explanatory! One thing I like about this pedal is that the knobs are more stiff than other botique pedals so that there is no chance that your guitar cable can accidentally move your settings while playing. Another feature is that if your using an AC adaptor the battery stays fresh and won't draw power from the battery.

This is where the OCD shines! The equipment I used to test the OCD are as follows: Carvin Belair 2x12 amp, Fender American Stratocaster Hardtail with a Seymour Duncan Jr. JB in the bridge (mini-humbucker). Very responsive in every setting. You can get that SRV sound to the AC/DC sound! With the HD and LD settings it's like having two pedals in one. It nails the British sound in the HD setting while maintaining your natural guitar settings on the LD setting. You can also get a bit of a "scooped" sound on the LD setting and a bit of a mid-boost on the HD setting. HD=Marshall or Vox and Twin or Tweed on LD setting. The best feature on this pedal without a doubt is that you can keep this pedal on and get a clean, Texas Blues and a Fat overdrive/distortion just by using your guitar volume knob.

Effect is very quiet and built solid. Yet to play it live. I just got it but spen several hours getting some great tones! More to explore with more time.

I was really happy with my existing sound using the Xotic pedals for example: AC Booster and RC Booster pedals, but I was seeking some additional tonal flavors. The OCD fits the bill. The OCD can give you all the ballsy distortion and overdrive you need for most of your sound needs. Using the RC Booster in front of the OCD is a great addition adding volume boost and some extra grit if needed! I'll also continue to use the AC Booster for that signature smooth violin-like lead tone. The pedal the OCD replaced was my VooDoo Lab Sparkle Drive. I was getting a better SRV tone from the OCD hands down. In summary, if you are looking for a pedal with a lot of tonal options for you, this may be a great choice for your tonal arsenal. I highly recommend this pedal. The pick sensitivity and tones you get from just your volume knob will amaze you! Check it out! Rock on!!!

I wanted to add something to my previous review. Ivae OCD version 1. I read reviews that state the OCD doesn't get good distortion. I disagree because it gets a wide range from boost to overdirve to awesome distortion (subjective I know). I recently bought an Xotic AC booster and put it in front of the OCD. I turned on the OCD with the AC booster on and wow.... Creamy distortion oozed out of the OCD. I discovered that having a punched up signal via the AC booster changed the characteristics of the OCD. It truly added another level of distortion versatility. Very cool!! It's a great pedal. I think you have to have an OCD in your chain. The question is what sounds better to your tatse -0 Version 1, 2 or 3. Someday I will get Version 3 just because I feel it has to be great beause it has a great lineage.

Easy to use, simple intuitive layout, effective controls. instructions minimal but are just enough to understand how it works.

I used this with a vintage strat and tele, both through a vintage Deluxe Reverb and a recent Crate V series 3112 with Tone tubby. Really it's own type of sound. Better used to drive an amp than as stand alone overdrive. Clean settings really effective. Overdrive leans more toward a fuzz than, say, a Tubescreamer. Higher drive levels become very creamy with alot of low end, but tone control adds highs that are on the harsh side. I foung it difficult to get much past a slightly broken up sound before loosing the best balance of highs, lows and mids. Very responsive to volume changes, attack and remains very clear until pushed into higher drive. It pretty much looses it there. Low pass-high pass switch is effective.

Seems very well made. Very quiet and solid. No issues with functional performance. Would feel confident that it is reliable.

Fulltone apparently has a reputation for making good products and having poor customer service. They offer various upgrades for some items, but never answered my emails. I eventually gave up on my inquiry, but would not have accepted that if I had a real problem.

I bought this from a dealer expecting a current model known as the Version 3. When I received the earlier V2, I gave it a really good try but didn't love it and ended up not keeping it. According to Fulltone's descrption of the changes to the newer version, I might be tempted to try another one as it seems to address what I felt were shortcomings. Would be nice to hear from them before I do it, though.

I have no problem getting very good rock sounds from the OCD. I own the original version. I think it is important to identify which version you are revewing because the Fulltone site explains the differences in components and sounds. Volume - Tone - Drive & a LP/HP mini toggle.

My fav artsist are Trower, Blackmore, Santana, Page, Townsend. I own Keeley modded Boss BD-1, DS-1 (Ultra Mod), VooDoo Lab Sparkle Drive Keeley modded TS-9 and others. The OCD is in a league of it's own in terms of transparency and tube amp like tone and versatility. I have many pedals because there is no such thing as the holy grail. All pedals offer unique characteristics and I appreciate all the pedals I own. I intend to buy the new Fulltone GT500 and perhaps the Fulldrive 2 Mosfet. The OCD has such an open sound. I find it to be very versatile. None of these other pedals mentioned above come close to it's transparency and tube amp like tones. With the drive at 100% on LP setting it gets a great natural amp like overdrive/distortion. Hit the HP setting and it simply increases the distortion level. Pull back on the drive and you get crunch or whatever OD setting you need. I doin't know if metalheads would be satisfied becuae it is not a supoer saturated distortion pedal but if you l like AC/DC, Zep or Deep Purple OD and distortion you will enjoy this pedal immensely. I like that the OCD distortion is not fizzy (with my rig). It has a amp like OD - sharp and biting. I mostly use it in the LP mode. It can be used as a clean boost by keeping the drive down and nudging the volume aboove unity gain to your liking and then setting the tone. BTW- the tone control offers a wide range of tones to compensate for your PUPs and amp. I run it through a Straub Cantus 50 El34 amp. What amazes me about the OCD is it sounds awesome whether the amp is set to clean or with the amp set to overdrive. I am always blown away by that. It cleans up nice when the guitar volume is turned down. It is hte most amp like natural overdrive distortion I have ever played through. If you have a good tube amp and you want to add flexibility as if you are adding additional channels to your amp, the OCD will definitley do the job.

So far so good - had it about a year but I don't play out so I can't really say. It seems like it is built to last.

Not usre about this. I emailed to ask the differences between the original version (mine) and the latest version and got no response. I eventually found the answer on his web site which is probably why he didn't repond. But a simple reply to say "check the FAQs in the OCD scetion of the site" , shouodn't be too much of an inconvenience. Oh well.

I play variety - beatles, purple, santana, sting and basically classic rock. Playing for 38 years. Have too much gear. My main rig is 1971 LP Custom / 90s Strat Plus w/Lace Sensor PUPs ---> Tonecore compressor ---> Keeley modded DS1 or BD-1 or TS-0 ----> OCD ----> Fulltone Choral Flange ---> Straub Cabtus50 (incredible amp). I would definitley buy it of it were lost. IMPORTANT to underdstand that there are three versions out there. Go to the Fulltone web sitre for the details. I am very curious to to hear the latest version. according to Mike Fuller it has "Stronger Mids - More Sustain - Better Tone Control". Sounds real juicy to me - DAMN!!Guess I'll have to get one eventually. If you review an OCD PLEASE indicate which version you have. Go to the Fulltone site to ID your version.

Easy to use, easy to get a good sound out of.

As others have said: 1. Great, really great clean boost. I don't think I really knew what that was before I used an OCD. 2. Excellent light and medium overdrive. 3. If you want distortion, this pedal doesn't really deliver anything GREAT. It works, sounds relatively good, but not GREAT. Different guitar/amp combos do different things, but for my rig - (strat/tele/DuoJet into a 63 Vibroverb) - no one was ever going to complement my tone using this particular pedal.

I already have a modded SD-1 and DS-1, so I've got a good range of overdrive, light and medium gain. What I was looking for was something to give me a new tone in the medium and high gain range. If I hadn't already invested time and money into the other two pedals, the OCD would have been a much simpler (and maybe preferable) setup. However, if you already have modded od and dist boxes, the OCD doesn't bring anything to the table.

Can't say on this one, but it seems more solid than a boss-type pedal

don't know

This pedal is ideal for someone who wants just one pedal to cover light and medium gain sounds. Can be substituted for a Tube screamer or a light distortion box like a DS-1. Works pretty well with tube screamers, but modded DS-1s compliment TS pedals better, imo. If you're looking for something to go along with your tubescreamer, look elsewhere, you can do better. If you need just one pedal to cover alot of territory, this might be the one.

Bottom line, I returned mine. It doesn't offer much more than what you can already get with a good tubescreamer-type pedal.

Very easy to get the tone I require. With my strat, I turn the drive up 100% due to the single coil pick-up to get the distortion, with my Les Paul, with has 57 classics, I back off on the drive to about 3/4 or less do the pick-up strength. Very basic controls ( Volume, Drive, and tone. Also has a HP (seems to give an extra boost to the signal) and a LP switch (leaves the volume very level or normal).

As far as sound quality, as many have stated already, it is very transparent. I am running through a Marshall 1987X 50 watt Plexi, so the OCD works great in front as a sort of preamp. The Plexi is very loud at lower volumes in a tight room/space and the OCD does the trick.

I bought a Fulltone Fulldrive II at first, but it didn't have the distortion I needed to drive my Plexi. The Fulldrive II had a very smooth distortion/drive but was limited for my use. To be frank about it, I thought my trusty cheap Boss DS-1 kicked its ass as far as distortion and attack. I sent the Fulldrive II back and exchanged it for the OCD.

Just bought it and no problems so far, Built very well.

Haven't had the need to deal with the seller or Mr. Fulltone, hope I don't have to.

I play Blues Rock and this pedal gives me the late sixites sound that I hear in my head. Although, playing in larger halls, my Plexi by itself doesn't need any help to get the tone I want.

Tweaked for half an hour. Tried through a couple of amps with various amounts of amp/pedal gain and tone. All sounds were good but it finally dialed in real nice.

I'm running an American Strat > Keeley Fuzzhead > Jetter Gainstage > Fulltone OCD > Line6 XLT (effects only, no amp modeling) > Fargen Bordeaux.
I'm using the OCD with the neck pup running thru the Blackbird (think Fender Deluxe) side of the Bordeaux. This is the most natural, smooth, bluesy overdrive I've ever played. It very much depends on you having good equipment cause it won't hide a bad amp behind lots of distortion. What this does is brings an already good sound into a beautiful, wide open, big sound. You can dial in quite a bit of distortion if you like, but the best tones are just pushing the amp a bit. I use it for that Clapton tone and it is just right for me.

Fulltone stuff is the best out there. I can't imagine this ever failing.

Never dealt with.

I've played for 37 years and I play mostly in church these days. I've owned lots of pedals, amps, guitars. I'm playing the three pedals I like the most. Each is on the pedal board for a specific sound. The OCD is for that smooth Clapton sound. It complements the other pedals I own.
If my pedal board were lost or stolen the OCD would be the first pedal I would reacquire.
I don't give out 10s but this may be as close to a 10 as I've run across.

A lot of ways to get sound from this pedal is both it's greatest strenght, and it's greatest weakness.

I personally feel the pedal has too wide a range, making it so that if you nick a knob and it turns slightly your tone can change a little too much.

Overall an easy to use pedal... do yourself a favour and run it in 18w mode though.

I cannot stress enough how important it is to run a pedal for a while before you decide how 'sweet' it really is. After the initial hype wears off, you'll realize what the sound quality really is.

My rig consists of a Vox AC30 from the 70's and a Gibson ES-335 with a pairing of Burstbucker Pro's installed in it.

I find the pedal can be quite transparent in lower gain, or clean boost settings. Being used as a clean boost, or something to hit the front end of your amp harder so that it goes into a natural tube overdrive is what this pedal definatley excells at.

When you start getting up into higher gain territory the pedal starts loosing a lot of top end, in fact I have the tone knob set to 3:00 and the drive set to 10:00 and I'm getting a huge low end rumble from the pedal. Diminished chords seem to get lost, and the response becomes very 'solid state' feeling... Especially in the LP mode.

Switching to HP and upping the tone to 4:00, backing off the gain a bit, gave me a really nice heavy high gain tone that still had some top end sparkle. Very balanced, but not transparent in the least bit.

Compared to my Crowther Audio Hot Cake (a very simliar sounding and responding pedal) the OCD is in a distant second. The Hot cake is just simply more expressive, more transparent, and just overall a nicer sounding box.

Don't get me wrong, the OCD is a great box. I hate most distortion boxes, and have been relying on my Hot Cake for years, but now I finally have another box that I can use with my Hot Cake for more versatility.

seems well built

never delt with the guy

I play a lot of rock music, but my influences are from punk, metal, blues, and classic rock; and my writing reflects all of those, so I need something versatile.

I wish the OCD was more versatile... more like my Hotcake (in fact I ordered another hot cake to replace the OCD the other day...I'll still keep it in the board though...)

The ability to run it on various voltages, and the huge sweaps is both a nice feature, but also frustrating... its a good pedal, and I'd miss it if it were gone. But overall I think for the money there are better boxes to get... the Crowther Hot Cake for $20 less is a good place to start...

Real, real easy to get a great sound out of it immediately.
I couldn't wait to get this in the mail.
When it finally came, I plugged it in and just LOVED it right away.
(Just the opposite of when I plugged into a Danelectro Daddy-O, what a complete total piece of absolute crap).
There's no manual, just a two sided printout about the pedal in general. You do not need a manual. Just play it and twist knobs. It sounds great. The knobs have a nice feel to them BTW. Nice firm tapered feel while turning them and a little tweak makes a difference too.. Very nice. I'm going to be giving a lot of 10's in this review. If that bugs you oh well.......

The OCD does not sound like a pedal. I recently bought a Reissue Bassman LTD. and needed something for low volume situations when you can't crank the amp for overdrive. I tend to HATE pedals. They all sound like absolute crap to me. I hate Tubescreamers, Rats, Expandoras..all that junk. THIS sounds GOOD! Not 'pedal-like', sounds like my Bassman turned up lound if you set the knobs right (Drive fairly low sounds killer to me but if you want more, it's in there and it sounds good too). Now if you 'shred' or want to sound like Slipknot or some crap like that you may not like this pedal but if you like REAL music and musicians like SRV or Clapton or Walter Trout or Robben Ford or Chris Cain or Tommy Castro or Johnny Winter or Buddy Guy or even Gary Moore's bluesy stuff you might just like it a lot. I do. As I said, so far I like to set the Drive low (about 9:00) the Volume about 10:00
and the Tone about 1:00 and then turn the guitar volume knob down a bit for cleaner tones.....or crank it up to wail on some blues riffs.
Sounds an awfull lot like the Bassman screaming on about 6-10. Very organic sounding. Very responsive to your touch. Very amp-like.
It's not noisy. It's got a COOL blue light that gets seriously bright and throws all these little rays out (real trippy). It sounds great with it set on LP or HP equally. I kinda like the less in your face tone of the LP..........or do I? It's just a blast to play if those are the kind of tones you seek and don't want to sound like you're playing through a crappy pedal. It seriously sounds very much like the Bassman turned up real loud and distorting even with the drive set pretty low...amazing.

Feels and looks VERY solid. Nice heft. Very quality feel and sound.
And did I mention the blue light? Real unique and hard to describe. It's not a regular ol LED type thing. Very, very cool.
I can't afford two of them so yeah, I guess I'll use it without a backup. I can't really imagine anything going wrong with it, it seems real solid.

Wanna try the higher power adapters they say you can use.
It can take 9-18 volts! They say it gets even better sounding
on higher voltage.
They even include a battery in it out of the box. How many effect
manufacturers do that? Yep, comes WITH a battery.

I play Bluesy styles primarily as well as R&B and Soul and
Gospel type stuff etc. You know styles that are all about cranked
Fender for the most part or Marshalls and such. Edgy breakup to full
out power tube wailing. This is a great match for those styles. Think Clapton on his "From The Cradle" album.....it does that style of overdrive and more.
I've played for like 40 years I guess? OK electrically maybe 30? Long enough to develop strong opinions aye?
The only thing I wish it had is another footswitch button to select between LP and HP modes instead of the little toggle. That would be cool. I tend to put the pedal ON the amp anyway though instead of on the floor so I don't have to bend over to knob twiddle so maybe it's ok. I can just reach over and tweak it. It is a little small though and kind of between the two top knobs. That's my only complaint really.
What I love about it really, as I already said, is that it doesn't sound "pedally". It doesn't sound transistory or thin or buzzy or any of that junk you get with so many overdrives/distortions. If you're more into Freddie King than some goth-metal shred dude you'll probably like it. I can now gig with the Bassman at low volumes and still have convincing power tube crunch and overdrive when I can't turn the amp way up like I would at loud blues gig or an outdoor stage gig. I'm stoked.

I've owned this pedal for two weeks and waited until now to write a review.

The only reason I'm giving it a 9 is that 18 volt adapters are not the most common and I don't own one yet. I am ordering a Dunlop DC Brick for my pedalboard to do so. According to fulltone the unit sounds better with one. "You'll be amazed at the sonic differences. The higher the voltage, the cleaner, louder, and more dynamic the sound, kind of like the difference between a 50 and 100 watt marshall."

I plugged this in originally using the suplied 9volt battery my chain was as follows:

Ibanez artcore 75 (335) with dunanc HB102's> Monster Cable 'rock'> OCD> Monster Cable 'Rock'> Laney LC50 (6L6 power amp)w/ Eminence 'the wizard' (clean channel with volume at 3)

I started out on the LP setting with all knobs at 12:00 and....................................................:

Pure Bliss!!!! Great cranked amp tone, very dynamic.

I then turned the unit off and switched over to the amp's dirty channel and tried to recreate the sound with marginal success. I couldn't get the same complexity and detail with sustain, it was close but not as good as the pedal.

I then tinkered with the gain and level eventually getting to where the gain was dimed and the level was about 10:00. This gave me only a slight boost in volume when turned on.

At this setting the amp sounded like a cranked vintage marshall/ hiwatt but I think it was even more articulate than the actual amps. My subsequent attempt to recreate this tone on the amps dirty side w/ out the pedal was a complete let down. I even inserted a weber load dump and cranked the amp but could not get a smooth and articulate sound like the pedal produced.

I then flipped to the HP setting and found exactly what I was looking for, Soldano type saturated smooth overdrive with every note ringing true.

With the gain cranked on HP and the level around 9:00 (give or take :30) Tone still at 12:00 I got ripping overdrive/ distortion that was not super high gain but was plenty for my taste. I would say it's on the level or slightly higher gain than Warren Haynes when he plays with gov't mule. Keep in mind this is with fairly high-output humbuckers. You certainly have enough gain to play almost any rock including GNR and Tool. If you think you need more gain then you probably aren't good enough (no offense) to cover those bands anyway.

I a/b'd the OCD a week later with my Tonebone Classic through the same amp with the same cables but brought out a few more guitars:

MIM tele deluxe w/ fralin blues specials
2004 Les Paul Studio with 490/ 498 stock pups
2006 Fender Deluxe Players Strat with Vintage Noisless (stock)

On all four guitars the OCD sounded much more natural and open making the tonebone sound slightly compressed and solid-state-ish. The OCD was slightly more dynamic and articulate, although the Tonebone had more gain for sure. The extra gain proved to be of use with the single coil guitars as you can dial in some great raunchy classic rock/ shred tones that are not available on the OCD with single coils but the humbuckers get muddy at the same gain levels IMO.

So to sum it up I think the gain on the OCD is more of a mix of the sound of preamp and some poweramp distortion while the tonebone is pure preamp especially at the high gain setting.

I also prefer the sound of a wah (535Q) into the OCD better than the tonebone which tended to get a little 'quaky' for me.

I didn't have noise problems with either pedal.

It hasn't left my house and it's still workign great so I can't comment. Although the pedal seems fairly simple so it is probably more reliable than my old tonebone.

I play a bastardized version of rock/ funk/ blues/ jazz.

Some guitarist whose tone I admire:

Steve Kimock
Michael Houser
Mark Knopfler
Warren Haynes
Jerry Garcia
Derek Trucks
Jimmy Herring
Marc Ford
Charlie Hunter
Jeff Beck
David Gilmour
Eric Krasnos
Adam Jones
Nils Cline
Etc.....

For now this is exactly what I was looking for in a overdrive/ distortion pedal:

1) touch sensitive/ dynamic
2) Smooth or chunky depending on guitar and settings
3) small
4) uses 9 or 18 volt adapter (tonebone needed wallwart 15v)
5) Sounds like an amp and not a 'metal zone' etc...

Dead-easy to elicit great sounds: all controls work on a very wide range of possible settings.

I just got one it does just what I want it to: faux AC-30 sounds from a Fender Blues de Luxe. Even with a Roland micro cube and a Tele I was able to get that Syd Barret sound.
This is the most touch sensitive pedal I have ever played with; from a light crunch to a nice bite just using your attack.
Sounds great with any guitar ( P 90 sounds fat yet open, a Tele can really sparkle without sounding harsh).
The higher gain settings are good but this pedal excells in the Goldielocks-zone of crunch.

Built like a tank. You could probably use it as a hammer and only damage the paint. Use it with care and I don't think you'll need a backup.

Sorry, no experience with customer support.

I've been playing for over 30 years now and at the moment I'm in a Blues band. We do some R&R, Country and Pop songs and that's where the OCD comes in very handy. It works very well with other effects like chorus, delay and reverb and with this one your sound won't clutter even if you decide to use'em all at the same time for that dramatic solo.
I did contemplate the purchase of an AC-Tone by Carl Martin but I came across this one first (Sorry Soren).

Easy to use

Here's where I depart from the crowd. The OCD is quite useful as a transparent clean boost, but you would literally have to be on crack to say it sounds like a plexi Marshall. I found the overdrive sterile, fizzy and actually "solid state" sounding. I prefer my Boss BD2 with a Monte Allums mod, which is like a Keely or Analogman mod, but $20 instead of $70. Bottom line, $160 is simply too steep for a clean boost. Again, if you expect a solid state device to sound like an overdriven tube amp, maybe it's time to give the pipe a rest.

Seems solid.

Never had to contact them.

I'll give it an 8 for solid construction and quality components, which clearly contribute to the "clean-ness" when it's used as a clean boost, but as I said, the overdrive is just so-so.

extremely easy to use. Tone Drive and Volume knob, and a switch for high and low power.

Great for blues. I can nail clapton, SRV and many others. More importantly, I have the sound I want. Very versatile, slight movement of the controls get very different sounds. Very responsive to pick strength. True bypass is great. I use this with either a digitech RP200 on cleans for quiet practice, DI box for recording, or into my Fender Hotrod Deluxe. It sounds great with whatever I use it with. Does have the ability to do a huge clean boost.

Very reliable, very well built. I gig without a backup because this is my only pedal. I waited 3 months to get it after trying it (it sold out at the shop before I could buy it) and it was worth the wait.

Overall Great pedal. I would definitely replace it if lost, I love everything about it. Compared it to all the pedals I could and this one broke the mold.

every increment of the knobs does something good as in you dont have to look for the sweet spot because the whole thing is one big sweet spot.

i play a fender koa strat into a fender blues deluxe amp. this pedal is the answer to my quest for tone. the hair on the back of my neck was standing on end when i tried it out at the store. i was ready to take the plunge and spend $200 on a Fulldrive 2 Mosfet when i decided to also try the OCD. i loved the fulldrive but i felt the the OCD had a bit more range of tone to it. this is the only piece of equipment i ever bought that i only have absolutely nothing negative about. i recommend you go and buy one and dont't even waste time trying. what ever type of overdrive tone you are looking for lurks within the heavy gage steel shell of the OCD. my only complaint is that i don't have two of them, one for light drive and one for nastier overdrive.

if i where in a death match where the only weapons you could choose where effect pedal, i would choose a fulltone pedal.

i get the feeling like i may never find out. though i might just email the folks at fulltone to thank them.

truth to tell, a decent strat, a decent tube amp, and a fulltone OCD are all i really need... and it only cost as much as 2 boss pedals that i would like a lot but never be completely satisfied with.

(bowing in the direction of the fulltone factory)

Easy to get good tones.

Here's where I'm gonna depart from the crowd. What Harmony-Central needs is a honeymoon policy, which should say "DO NOT REVIEW THIS PRODUCT UNTIL YOU HAVE OWNED IT FOR 30 DAYS, OR USED IT AT LEAST A DOZEN TIMES." The OCD sounds good, but not great. I found it most useful as a clean boost, at which it clearly--pun intended--excells. It is quite transparent when dialed in to minimal drive settings. When you begin to inch up the drive--on both toggle settings--the pedal becomes, for lack of a better description, "sterile". It doesn't sound ANYTHING like a tube amp. In fact, I'm frankly sick of claims that solid-state pedals sound like tube gear. They don't. If they did, then any decent amp manufacturer would be able to create a killer amp with a solid state front end and a tube power amp. But they haven't and they can't and never will. So that's my little tirade. In any event, if you want a good transparent boost to push your tube amp over the top, get a used Boss BD2 and mod it with the Monte Allums H2O mod.

Solid.

I'll give it an 8 because it's well made, true bypass, and sounds good.

very very easy Volume, tone, gain and switch Down American amp tones Up British amp tones. BLUE LED and built like a little tank.

I HAVE A first AND THE 2nd VERSION. That is the reason I am posting my review, to set all the hype about the new version. I used both with Tele, strat, les paul, Es-335, PRS p-90's, 59 Tweed Deluxe, Kendrick tc 2x10", Bad cat, Fender, Marshall and Two Rock. I like the 1st version the best, is a better boost, Better for solos or Rythm, the 2nd version is smoother maybe like a tube screamer but if I want a Tube screamer I go and get one. Is not as good for solos specially and it sound great. Because the OCD is about the very best you can buy. I will only put another overdrive/boost pedal in this category. 1- ocd 1st version + Throbak Overdrive boost 2- ocd new version 3- ts-808 + klon + boss sd-1 + burriss....I hate to say it but MIKE FULLER finally did it.

SO FAR SO GOOD

WELL I MUST SAY HAD A FEW BAD EXPERIENCES WITH MIKE IN THE PAST. BUT THE VERY LAST TIME I SPOKE TO HIM IS LIKE A CHANGED MEN. I AM WORRIED BECAUSE IS HUMAN AFTER ALL.

THIS A KEPPER AND I WOULD GO TO THE END OF THE WORLD TO GET ANOTHER ONE OF THIS OCD PEDALS.
KILLER KILLER KILLER

Easy to dial in!

I got a great deal on this OCD pedal.
It's Hands down the best pedal Fulltone makes.
It is transparent but a little bit fizzy in the hi-end department.
I did an A/B test with my other pedals & it does hold up well, but
not enough to keep it. Rock, Hard Rock, Punk Rock, Blues it can
do all that. It lacks it's own distinct tone. The toggle is cool
& very usefull.

I'm sure it would last forever.

Pretty cool to deal with.

I use 2 pedals in my set-up. One Overdrive pedal in front of my
Bassman or Bandmaster & one overdrive pedal for solo's. I play
Hard Rock/Punk/Alt Country (it's all just Rock music to me).
The OCD sounds good, but there are many other pedals out ther that
kick its ass. Maybe if I would have bought this pedal before I tried so many other Fulltone pedals it would stick around. It's better than any modded pedal you'll ever find. Try one out for yourself & make a decision. Barber, MI Audio, Aramat & HAO to name a few make incredible pedals. You may end up trying them all like I have.
Thank god for Ebay. I would not buy this pedal again.

easy as pie to use. use your own imaginative and creative mind.thats why we buy different effects right? im a high gain kind of player and it seems most boutique pedals are geared for that (vintage tone). anyone notice that? anyway, the OCD is an awesome pedal for high gain usage. and not so high gain. i emailed Mr. Fuller about the use of the OCD with humbucking pups. his reply was (the OCD works perfectly with hums).

he was so right.

what an awesome pedal! again, i like a high gain pedal and this is great for that. and also it can be tamed down nicely as well. very tweakable. i use it through a modded hot rod deluxe, and a soldano astroverb. it kills with both amps.

no noise that i could detect.

im a 27 year player and electronics maniac. everything i have ever bought i tear open to check out the build quality. the OCD is a heavy pedal. that is because its built super solid! the inside is awesome as well. top notch components and excellent workmanship!

Mr. Fuller if you read this, thank you sir for building a superior pedal with the OCD.
im as anal as anal can get with my gear. the OCD was perfect right out of the box. also the guys at Humbucker music for which i bought it from are fanatastic people!

havent had to deal with customer support. but i can tell you that Mr. Fuller will answer your emails pretty promptly if he can. he did mine! and i ask some to the point questions! Fullton also puts mods and other tech tips on his website. thats a fantastic gesture.

27 year player here. i know my gear and guitars. Fulltone products are an example of (made by musicians for musicians). superior build qaulity and components. the OCD is a fantastic pedal for high gain and not so high gain distortions. and the high/low switch rules like perfectly! as with most products you get what you pay for. the best 160$ U.S. i have ever spent!


thank you Mr. Fuller! you rip man!

The manual was pretty much a waste of paper not because of the content because this pedal is so easy to get a good sound from.I bought the ocd without listening to it purely on the say so from my supplier and he wasnt wrong

I plugged it in and it gave me the sound that I have been looking for for a long time,it crunches it drives it gives that edgey dry vintage blues sound from my Marshall jcm900 and drives my boogie dc-3 into lonestar status.One thing that has really made this the one pedal everyone should have is it does`nt change the sound or character of my guitars,I have a Parker Nitefly and a Levinson blade they both have single coils , strum a chord and every note can be heard clearly not a mish mash as with the tube screamer,swithch to the humbucker on my nitefly and the sound is just warm and lush and again no colouration,you can change the tonal colour by playing with the guitar volume .this pedal is good ...no this pedal is sublime and if I had to keep just one this would be it

Can you depend on it? its built really well solid and time will tell if its reliable

havent needed it yet

I play everything from blues to folk to rock and back,I use to much gear to get the sound I want and this pedal has theoretically reduced the need for two amps...will I do that? NO cos I'm a gear freak but I will say that I would replace it,I have tried shed loads of overdrives and this is the only pedal that makes me want to write about it that puts it in a high value for money although its not the cheapest tart at the party it give the most bang for the buck

Pretty easy to use, some cool features are included, and the manual (while short) gives you more info than a Boss manual, and its' easier to understand!

The most beautiful thing is it will work with pretty much ANY adaptor between 9v and 18v. Sure the sound changes, but it makes it killer for gettting it running in a snitch.

Oh..and it's uber easy to get a great sound...not just good, great!

It's pretty killer that this pedal provides almost no mud, no matter where the dials are set. In the LF mode, it really dosn't effect your input signal all that much, but boosts things instead. Very transparent, and probably the most useful for me.

When you thorw it into the HF mode, it really opens up! The gain you get is very comparable to Plexi...bright but dark. And it is incredibly balsy and deep! It takes me AC30 and puts it right up there for high-gain agression!

All in all, I'm running this thing w/18v's, in HF mode, with just enough gain for it to still be smooth with my normal heavy handed attack, but when I really dig in it gets crunchy with some amazing mid-range!

seems more rugged than any other pedal I own

can't afford a backup...yet

Mike Fuller is an interesting character... fun to talk too!

This is a real kick ass pedal! I've been searching for a long time for a pedal that is smooth, and full sounding, with a lot of defintion for nice dirty jazz chords, but not too bright. The only other box that I've found that provides this is the Crowther Hot Cake, and that I like better for my lead, high gain tones, so I needed something for 'bluesy' drive...and this is it!

My rig is a stereo setup of an AC30 and a JCM900, acompanied by a Gibson ES-335 w/burstbucker pros, and a Gibson SG Suprmem with P94N and Superdistortion

Step on it and leave it on. It loves yer volume knob, responds beautifully.

With a little tweaking it sounds gorgeous. A Paul sounds like a Paul, a Strat like a Strat... you get the picture. Doesn't color yer sound at all.

100%

Haven't had to contact him.

Buy it now and leave it on. You won't regret it.

Very simple to use. You have your basic : Gain, Volume and Tone. Also you have a HP/LP switch. I'm sure all the previous reviews have covered this.

I had heard about this due to the hype surrounding it so I went ahead and bought it.

I play a number of guitars but mainly a Richie Sambora Fender Strat Mk II, Tom Anderson Classic T and a Gibson Historic '59 Les Paul Reissue. These are played through the following amps : Fender Twin Reverb (Silverface), Fender Blues Junior (this is what the majority of the review will be on), Fender Tonemaster and a Cornford Hurricane.

I play Classic Rock/Blues/Pop and the occasional bit of metal.

As for the gain this thing has a TON of it on tap. This is the first pedal I've actually been able to get a really decent metal sound with. It really is incredible, just crank the gain and blast out some Iron Maiden, it does it !!!

As for low gain stuff I don't think it's so great as with the gain off it still has too much gain. I guess it's more of a Distortion than an overdrive but don't let that put you off as it does a good low gain just not low enough. Hopefully my incoming Fulldrive 2 Mosfet will settle my needs there.

The pedal is also very amp like in the fact when you turn the volume up you get more gain so if you turn the gain up the volume needs to go down on the pedal. It can clean up very well with your guitar too.

Haven't really got much more to add but it covers everything from low/mid gain territory up to metal territory (Iron Maiden/Metallica not insane drop stuff) and is VERY quiet unlike most other pedals I've tried.

Built like a brick shit house. You could drop a million bricks on this thing and it'd still work.

Haven't dealt with Fulltone.

On a whole I think this is definetly one of the best pedals ever made so if you're in doubt about the hype just go an try one out and see for yourself how good it is. However if you really don't need high gain maybe take a look at the Fulldrive 2.

Easy to use. Bought this in late 2005

I am a sucker for a strat or tele into a tweed bassman. This basic clean tone is the best. It's that 4 10" swirl - large sound - fills medium sized rooms just right. I need the right breakup pedal for my bridge PU and have tried a thousand ( ok - maybe 20 ) pedals over the past 30 yrs.

strat ( EJ ) or tele >>>>> Carl Martin limiter ( subtle amount of compression always on - just enough to even the transients a little ) >>>>> OCD >>>> old analog ibanez delay box ( AD 99 ? ) >>>>> bassman

Not at all noisy. Very nice OD pedal - one of the best I've tried - no mid-hump - responds to fingers / pick well. Bridge PU rock stuff is good with this box. neck PU - not bad for blues either.

Maybe 10 gigs with it - much use - very dependable.

I have ownded maybe 6 Fulltone pedals - well made - never needed tech help.

I've played 35 yrs - past 10 years in cover band - all the goofy dance stuff - R+B / rockabilly / rock / - 1-2 gigs per month.

my quest for the right OD pedal to go with a single coil guitar into a "lots of headroom" amp ( I don't know anything about humbucker, marshalls, etc - very different deal ) has included:

1. Budda phatman
2. TS10
3. TS9
4. Maxon OD ( big green box ? model ? OD 820 )
5. OCD
6. black cat OD 1
7. real tube ( years ago )
8. Keeley mod Boss blues driver
9. Carl Martin ( drive and boost )
10. Fulltone distortion pro ( the red box )
11. 3 different treble boosters - Keeley, Germania, Crispy creamer
12. Big Muff
13. blackstone mofset
14. more I can't remember


AND THE WINNER IS ! -- Keeley mod BD2 - hands down. But the OCD is a close second - also it holds it's value - decent $$ return on ebay.

I am using this pedal with a Rivera Quiana Studio 112 and a Bill Nash Strat. As far as ease of use goes it is very simple and straight forward with a very low learning curve. I give it an nine because you cannot switch from low peak to high peak by stomping on a switch you have to bend over and flick a switch. More on LP,HP below

Love the sound. I use it mostly on the fender side of my amp and 90% of the time I use it in LP or low peak. Here it does not color the sound of your amp and guitar it just gives you more. Very transparent and cleans up great when you back the guitars volume down. I usually leave the gain at about 10 O'clock and the volume on about 10 O'clock. There is a tone of gain and volume available here so you do not need to jack the thing. In HP or high peak mode it colors the sound more but..........If you turn the gain up a little say about 1 O'Clock and turn the Tone knob down to about 10 O'Clock you can get an absolutely huge fat sound for single not lines while still retaining some definition and stringiness, definitely a 10!

No problem yet. Seems to be built really well. I did get a bad PS1 power supply though and they fixed it at no cost reasonably fast. Since I am reviewing the pedal and not the power supply I am going to give it a 10

Fulltone's Customer support was great on the power supply. I bought it from Musictoyz and frankly they were unresponsive.

10. Is lost or stolen. I would shop around and see what's out there. I would like to check out their Fulltone Drive II MOSFET pedal or a Zen Drive but I would not be surprised if I ended up with another one of these. Just a great pedal I highly recommend.

3 knobs, one dipswitch. It's pretty straightforward. This thing is a time vortex though. One thing I will say is watch the hp/lp switch. The high peak sound can get mighty bright with any open back 2x12 amp.

It sounds great as a clean boost for the front end of my AC-30, and the breakup at low gain settings is extremely toneful. The higher gain settings are out of this world. The breakup is so musical I almost couldn't believe my ears. Theres a certain harmonic saturation to it that I didnt think could come out of an effects pedal. And the responsiveness to pick dynamics and volume controls is really remarkable. It cleans up nicer than any drive Ive played to date. I play a variety of instrumental space rock/alternative/indie and some heavier prgressive stuff. It cuts the mustard in all regards. Ive gotten a great SRV voodoo chile vibe out of it, and I've gotten a great early pumpkins Cherub Rock tone, too. So the versatility is there 100%. Throw in a hardwire bypass and a sweet blue LED and Im pretty much sure this guys got a permanent spot on my board, until I cant play anymore.

I work in a store that deals fulltone pedals. Ive opened up almost every one of the fulltone line of pedals, and I havent seen a bad solder, pot, resistor, switch, cap or board. The wiring is all clean as a whistle, and the work is impeccably clean. Not to mention the ridiculous steel chassis. You could use this thing to rob a bank.

Ive talked to mark and andy(?) at fulltone and theyre both stellar guys. And they mail parts really quickly.

I play a variety of rock music and a smattering of pretty awful imitation blues. Ive been playing about 15 years now, and I went to school (albeit shortly) for music. I mainly play a 70's strat or a G&L invader into an AC30 with any number of effects, though usually its something like Ernie Ball VP Jr.->BBE Opto-Stomp->Keeley Blues Driver->80's Rat->Fulltone OCD->USA Smallstone->Behringer UC-100->
Boss RV-5->Line 6 DL4->Line 6 DL4 (Yes theres two of them.) It made my rig into a rock machine. Its exactly what I needed to get the tone I was hearing but never quite getting. If it were stolen, I would curse the gods, and hunt the bastard down. I dont believe in backups (because Im poor) so it would be a nightmare to replace. I love how responsive this pedal is to input dynamics. Ive read the other reviews, and I cant see how someone wouldnt like this pedal. Unless they have absolutely no nuance in their playing. I honestly only found a bad sound with this when I dimed the volume and tone and had it set to low peak. I made every animal in a 4 mile radius pee on a rug. It was EXTREMELY bright. Ive compared this to every tubescreamer, od-1, keeley ds-1, rat 2, every drive pedal I can think of. Its the mustard on the tone sandwich.

Only three knobs and a switch, if you can't figure this pedal out you should probably be a drummer... :)

Mike should call this thing the "OMG" (Oh My GOD!). This pedal is completely natural at lower volumes, and doesn't color the sound at all. You can actually back the volume down and get an IDENTICAL clean sound from your amp and then use picking dynamics or the volume knob to go from a whisper to a roar. The pedal absolutely RIPS at higher volumes. I play it with a PRS McCarty and Custom SE, Fender Eric Johnson Strat and 52' ThinSkin Telecaster and it is extremely musical with all guitars, although arguably better with the humbuckers and a little bright with the single coils. I have used it with all kinds of Fenders and Marshalls, although the OCD through a Fender Bassman LTD is a match made in tone heaven. The pedal has a real organic sound and is the closest thing to a "Marshall in a box" that I've ever used. I currently own and use a Klon Centaur, Keeley DS-1, Keeley BD-2, Fulltone Fulldrive (3 different versions), Digitech Bad Monkey, Visual Sound Jeckyl and Hyde, Ibanez Tube Screamer and about 20 other boost/OD's and the OCD is probably the best of them all.

Built like a bunker, I have never heard of anyone killing a Fulltone pedal.

Mike Fuller is a little quirky but if he keeps putting out pedals like this I think he's entitled to be a little whacky. Guy can play like a Muthah too!

I play all kinds of music from acoustic to blues to jazz to rock. I also do a lot of session work with critical ears and need to be able to ape various styles without bringing the whole house with me. If I could only bring one pedal, the OCD is it. I am kind of curious how this pedal doesn't have higher ratings, I suppose different people are looking for different things. The only criticism I can think of is the price, but I'd pay double for another if that's what it took.

Highly recommended.

3 knobs, meaningful labels, turning the knobs actually alters the sound (unlike so many pedals...). Stomp switch is nice & solid.

This is truly what I was missing. I play an SG with a Mesa/Boogie, and Boogies have a sweet sound but are by design under-driven. The OCD gives me what I've been missing for the past 15 years. It's amazing how the OCD provides drive AND improves tone. Even if I were not looking for drive I'd still use it for the improved tone.
I bought this because Trower uses it :)

Solid & reliable - no backup pedals needed.

Never used it

Buy one. Period.

Pretty familiar setup if you have ever used overdrive/distortion pedals before. 3 knobs Volume, Tone, and Drive ??? all pretty self-explanatory and they perform, as you would expect. There is a mini toggle switch to set between LP (Low Peak) and HP (Hi Peak).
The HP setting yields more volume, distortion, and mids ??? class A characteristics, while the LP acts as the opposite (less volume and mids, etc)

Pretty easy to use and get good tones from quickly. Also, might I add that there are a variety of good settings, not just one or 2 sweet spots that you need to dig around for.

Finally! It???s over! I am done searching for an overdrive pedal that meets my ears expectations. My experience during my overdrive/distortion quest has been this: I have found so many pedals that act great as a boost and add gain and sustain. However, it has always come with compromise ??? tone coloration, loss of bass, and at times harsh ice pick mids. Also, this is the first overdrive pedal I have found to work with chords and rhythm playing. You can use this pedal like a distortion pedal over a clean amp and NOT SOUND like the bottom is cut off with an exaggeration of harsh upper mids???REALLY! This pedal makes my Fender Blues Deluxe very Marshall like (ACDC grind no problem set the drive around 2 o???clock) Here is a good test for transparency???.turn the drive all the way down, adjust the volume to match your amp, keep the tone knob around noon, LP setting ??? play something and turn the pedal on and off (repeat) Do you hear a difference??? I haven???t on my fender or my Reeves Custom 6. Now raise the volume level for solos and you have a pretty darn transparent boost. This is also the smoothest overdrive I have heard???.period ??? and at loud volume too. Never harsh, never offensive.

Haven't had it long.... but it appears to be very well made - don't expect problems but can't really rate yet.

Can't say.... Never dealt with them.

I have been playing for about 20 years on and off and am by no means a virtuoso. I play Fender strats, epiphone paul, and a frankenstrat thru either A Reeves custom 6, Fender Blues Deluxe, Peavey Bravo, or Vox Cambridge AC15 (cheapo hybrid practice amp). I played in a cover band for about 4 years, but now just for myself and campfire parties with friends. I am a solid rhythm player (singer) who is finding my way thru solo and lead work. That being said, I have a pretty good ear (they are a little big and stick out too)

This is a great pedal???. Period. It???s transparent, amp-like, and versatile as both boost, overdrive or can act as a ???dirty??? channel to you rig that won???t hurt your ears or make you feel inadequate when striking more than 2 notes at once (chords).

You know when I knew this was the pedal? When I noticed the smile on me face after about the first 3 minutes of use. I never want to turn it off! Better stock up on 9volt batteries.

If it was lost or stolen??? I???d hunt down the guy who took it and make him listen to me practice tremolo (speed) picking on the high e string thru my battery powered Vox AC-1 amp with the treble cut all the way off, then I???d slam the front of the 1 watter with a TS9 (all setting dimed out) while he holds the amp to his ear.

I would certainly replace, I am even considering buying another one ??? just in case..

I am sure there are other great overdrive pedals out there, but this one works for me, and I don???t feel the need to continue the ???overdrive??? search anymore.

I don???t know what else to say expect for here is a list of pedals I gave up on: Ibanez TS9, Keeley moded TS9, Boss Blues Driver, Boss DS-1, DOD YJM308, Snarling Dogs, some others I can???t or don???t what to remember.

Good luck to you

NOTE: I tried to submit a review a couple weeks ago and at the end I hit the wrong button and don't think it went through.

Ease of Use: Very easy to get a good sound out of this pedal. As a matter-of-fact, I think it's impossible to get a bad sound from it. I've tried every possible setting with my rig (listed below) and it just plain rocks!

Gear & Chain: American Strat w\Fralin Blues Specials> Keeley Compressor (4-Knob v.) > Keeley Java Boost > OCD (v. 1) > Keeley Fuzz Head > EH Deluxe Memory Man (stock) > Fender Deluxe Reverb RI w\Celestion Greenback speaker.

My 'sounds' I like are the sounds of the 60's and 70's (being born in 61 I guess that's what one would expect. The Classic Rock\ Heavy Blues Sound is what I'm after. Think: Black Sabbath, Steppenwolf, Iron Butterfly, Clapton, BOC, SRV, etc....

As aforementioned; this pedal is very versitile and extrememly easy for me to get great tone from it. I previously have been back and forth with Multi-fx's to Stomp boxes (too many times to count). I always seem to come back to the individual stomp box pedalboard because the quality is there (and it's old school which appeals to me).

The area of Overdrive \ Distortion is one that I've never, ever been happy and satisfied with UNTIL NOW. I've been through the modded DS1's, BD 2 's, TS 9's & 808 's, and others. While they all sound good in their own right; none can compare to the OCD.

The OCD is just the exact tone that I have in my head and heart that I've not been able to translate into tone from my rig. It covers everything from light OD to Heavy OD and Distortion. When used with the Java Boost and the Fuzz Head it's OVER THE TOP.

This is a very musical pedal. I've heard other reviewers say that about the pedals they were reviewing, but never have experienced it myself until now. My Strat sounds like a Strat at any setting with the OCD! Enough Said!!!

Extememly Well built.

They are quick to respond to emails and offer good advice and help. They are a bit "matter of fact" about their stuff; but they can afford to be

Overall: Pedals come and go (sometimes on a almost daily basis) but the OCD Stays!

Super easy

okay the whole thing about this pedal is IMO is dont plug it in to a totally clean fender (type) amp with brilliant high end and expect this pedal to sound good ... its gonna ice pick in the ears ya!!!
there's no mid range hump in it at all (like a tube screamer) this is both a good thing and a bad thing depending on how you use it .... I feel this pedal sounds it best when you are playing with a "darker tone" and then you kick this pedal on and it sounds fantastic, very transparent sounding ... I've found it sounds best with my old 73 50 watt marshall and a les paul... when I use it with my 68 super reverb and tele or a strat its not that great ... its a little too thin sounding for my liking ( i prefer the king of tone pedal with the clean fender amp ) .... I especially like the ocd with a good Strat and my 69 plexi 100 watt marshall. the tone is great especialy when the "gain" on the pedal is backed down to about 2 o'clock and you ride the volume pot on the strat you can go from a great clean tone to a smokin tone ... i also prefered the hp better then the lp

This is made really well as far as I can tell ....... I dont anticipate any problems

never dealt with the company

I've been playing guitar for 31 years and I make my living playing guitar I do over 300 gigs a year and i've worked with many different artists over the years.
I play all styles of music and i have many guitars and amps too many to list here .... i like the ocd pedal. i use it occasionally for certian tone. i use other pedals more frequently like my analog man king of tone, ts9 with the silver mod, Klon and a keeley ts9 3x saturation.
overall this is a good pedal for a great in your face tone IMO ... i like it much better then my analogman modded ds1

I keep the volume at 9 o'clock, gain at 1 o'clock and the tone at 1 o'clock - I like the HP setting as it has the crunch that I like - EASY TO USE BUT LIKE ANYTHING YOU MUST DIAL IT IN BASED ON YOUR EARS

A friend of mine Randy Jacobs of the Boneshakers turned ne on to this thing and I gotta tell you - it's a fabulous pedal, Robin Trower and Jeff Golub use these as well (just a point of reference)
this pedal has a crunchy yet clean overdrive that is fat and sustainy and badass what else can I say I use it in conjunction with my FD-2 and the two of them give me a balls out Hendrixy, Trower lead tone - I don't use it for rhythm though as it too dirty in a sense - my board goes like this Fulltone Wah>Voodoo Labs Microvibe>FD-2>OCD>Boss DD-2 thru a Fender VibroKing or MB 2C+ or Marshall JCM-800 2 channel w/ reverb 65' Strat or 73' Strat, G-L's cables, planet waves pedal board cables

No probs so far I drive my board with a one-spot (which is very good I might add)

I've had Mike Fuller fix my wah several times so I don't expect to have any issues should the ocd go belly up

I play in a gigging band in San Francisco called Fog City Soul Review and we do 70's/80's soul and funk - I'm primarily a rhythm player but I do get a chance to let it rip on occasion and the OCD is my secret weapon it just rips in a musical way - it just has A presence about it that is unmistakeable - I'm very partial to Fulltone stuff as his pedals are well made, look great and tuned for Strats. I have a Dist Pro that I like too but the OCD has a unique character that is hard to explain you simply have to get one and try it...At first I wasn't sold but when I took it on a gig it came to life and I was like WOW!!! a LIVE GIGGING SITUATION IS ALWAYS THE REAL TEST FOR ME...

Basic dirtbox features. The HP / LP switch is kind of nice. It might have been nicer if the power jack was towards the top of the pedal instead of next to the output jack. I have patch cables with angled tips so that *can* be a MINOR issue.

The quality of the distortion is very good. Dynamic and complex sounding, some amp-like qualities. Not a plexi by any means though, not that you could really expect that out of a stompbox. Otherwise the sound has a very clean sort of quality that makes it sound expensive, but it sort of lacks some mojo if you know what I mean (its a little sterile). Try and turn the gain up and this thing is an ICEPICK!!! I tried it with a variety of amps and guitars. Deluxe, JTM 45, telecasters, strat, 335. The pedal is an icepick. You can turn the tone down, but the sound gets dark and mushy before the painful high end resolves.

Compared to a boss pedal the sound quality is acceptable, but given the price of this unit and all of the claims mike fuller makes regarding its performance... 5

Very solid!!

Mike fuller is kind of an @$$. If you agree with me, but think you need to suck it up and depend on him for good pedals anyways, I suggest checking out some of the other boutique pedal makers. For just about every fulltone pedal theres another, similar boutique that people claim sounds better. Plus you don't have to deal with fulltone. I guess if you like to be a suckup though, fulltone might help you out if you ever had issues.

I'm sorry to say that I ultimately had to sell this unit on ebay. I could never get the treble properly balanced without sounding dark and mushy / sterile. It was just too bright for any musical style. If your amps is VERY dark, hey, maybe you'll be alright.

pretty standard od pedal layout. fairly easy to dial in tones.

i can see why tons of people love the OCD. very smooth, very "nice" sounding. i'm not going to say it's a bad pedal. it's just too "nice" sounding for what i need. too smooth for me(i know "too smooth, what are you complaining about?" right?). i need a nastier tone that i just couldn't elicit from the OCD.

i generally crank smaller lower wattage combos and that's where i get the bulk of my overdrive. i only use the stompbox to kick it up a notch for solos or particulaly "heavy" parts.

this is great stompbox, just not the right one for me.

very solid. very well built.

good box, well built, easy to use, very smooth sound. i simple opted not to use it because it doesn't deliver what i need personally.

current libe rig:
*70s tele with rio grande pickups
*'56 reissue les paul gold top (p90s)
*boss tu-2 tuner
*mxr distortion+
*analog man modded boss tr-2 trem
*vintage ibanez ad-9 analog delay

It's a 3 knob overdrive pedal with a switch which changes the mid peak. pretty simple stuff.

Be careful here. I'll explain my situation. I live in Australia, so when it comes to brands like Fulltone, nobody over here sells them, so the only real way for me to try it out is to buy it online from musictoyz. I bought this pedal based purely on the amount of hype it gets. I figured i couldn't really go wrong. At the very least i'd get a decent OD pedal.
Essentially this happened. I got a decent OD. It's good, not great imo. Being Aussie, I've been using MI Audio pedals and in all honesty i think my Tube Zone and Blue Boy pedals sound much better.
Now here's the catch, everyone talks about the transparency of this pedal, and it's true the overdrive is VERY transparent, very touch sensitive and responsive to volume knob adjustments, which i use ALL THE TIME, it's probably my main tone shaping device actually. The problem i had was that these qualities were excellent, but the actual overdrive sound just wasn't that good. The MI Tube Zone just has a better overdrive sound, and it's still very responsive and dynamic, doesn't clean up QUITE as well but the sound is just hands down better, and most of the time i don't really want it to clean up completely anyway. I get many many comments on the tube zone, it sounds incredible, and i know just from listening to the sound of the OCD that it isn't enought for people to actually comment on.
Compared to a Boss this thing would still totally kick ass, but compared to my MI Audio pedals, i don't think it stands up. I'll keep it, but it'll be my backup overdrive.
I should also add that it's a much better sound for bluesy lead guitar. It's not really a rhythm overdrive sound. Tends to get lost in the mix and doesn't really cut despite having quite a lot of high end. I'd rather use an OD that does both lead and rhythm, ie the tube zone.
If you can, try before you buy. if you live in Australia, well you'll just have to take the plunge like me most likely. After all, 49/50 people seem to be happy with it, odds are in your favour! (or just get a MI Tube Zone and be done with it). If you try it and like it then by all means buy it and be happy.

Oh btw i play a 62 Reissue Custom Telecaster, into a 72 Fender Vibrochamp and 66 Princeton. So don't go thinking i'm using crappy gear, cos i'm not. I know good tone, and imo the OCD is really only about a 6. I'm not using it much.

Seems to be quite solid, Fulltone stuff generally is. It's well made.

I've heard that Mike Fuller is just one helluva busy lad, and appreciates not being bothered about trivial matters. i have no need to contact him about the pedal but should the need ever arise i will be sure to omit any comments about the weather, my girlfriend or problems with my car if i don't use premium unleaded. I'm sure he would appreciate this.

Really i've said what i wanted to say. It's a decent pedal, but i can't help but feel a little bit dissapointed. Everything i'd read led me to believe this pedal would set my tone on fire, and in all honesty this didn't happen, not even close. still, i'll keep it. it does have a fairly nice tone for a bluesy lead sound with drive ~3, but it's just not as exciting a sound as the tube zone. Sorry, i really wanted to like this pedal but it just needed to sound better.

Volume, Drive, Tone and HP/LP switch. The LP setting is a lower gain more natural sound. It adds a nice distortion without changing the sound of the guitar. The HP settings has a lot of boost and makes you sound "fatter" and in someways smoother. The manual is short and to the point but the best thing to do is just get the volume setup for unity and try it out. This pedal has a ton of boost to it so be carefull

I normally use this on a lower "distortion" settings. V 10 oclock, D 10 oclock, tone 11-12 oclock and the switch on LP. With a American Strat (with Lindy fralins) into a Dr Z Maz 38 sr this things is awesome. I can set the amp up to a nice clean sound and kick in the OCD for just the right amount of dirt. It really gives the sound of a tube amp being pushed hard. The distortion fades out nicely not like some pedals that have "ugly" tails to the distortion. I own a bunch of distortion pedals (TS9, SD-1, DS-1, 69 pedal, Distortion Pro, Sparkle Drive, Full Drive 2, Bottle Rocket, Screamin Blues and a bunch of custom pedals) and this is the best by far.

I have owned a bunch of fulltone pedals and they are built like a rock. The only backup you will need is a battery because you won't want to turn it off.

I have also email Mike and he has replied everytime.

I play blues/rock/jazz and this is a great pedals for that. It probably isn't a great metal pedal but that is not what is is meant for. I would buy another if it was stolen.

This is the ONLY pedal in my signal chain now!

Simple to use. 3 knobs. A switch for a gainier smoother (somewhat) sound. You don't want to just dime out the knobs, I keep the drive turned down between 2 and 6 most of the time, the tone hovers in the middle area. I like the HP switch position a little better than the LP unless I am going for a chunkier tone

This thing sounds like the amp is just turned up and breaking up on its own. It reminds me of a BF Fender super reverb cranked. Other reviewers have called the pedal harsh or complained about the high end, and it does have alot of high end and it is gritty , it sounds pretty much like a BF fender cranked up loud, if you don't like that sound, its the wrong pedal for you. It isn't really smooth, thats not what its for. I can smooth it out with my barber compressor, especially if I run the compressor first, but that spoils the point of this pedal. Its extremely touch sensative and dynamic, and it really doesn't sound like a pedal.
If you turn the gain all the way down and center the tone, and try to use it as a clean boost, its going to color the tone a little, but thats not what its for. I think alot of people who don't like this pedal are expecting it to be something other than their tube amp turned up louder.

You could use it for a hammer in a pinch.

I use it with my 63 Gibson Scout amp, running a 57 les paul special or a 71 strat into it. Both sound great but the strat especially likes this pedal. I didn't like it as much with my late 70s twin, but I don't much like that thing anyway, i think its the speakers. Sounds really great for my blues gig on that Gibson amp. This isn't a real high gain type pedal, again , it really is more like a 60s era tube amp cranked to break up, it is very sensative to what gear you run through it, pretty transparent. It has enough extra boost to help get my 17 watt Gibson amp over the drummer. Makes that amp sound alot more full and present also.
This isn't for metal or singing Santana stuff or phishyness, it is for a gritty detailed bluesy funky power tube type breakup. I haven't heard anything better in a pedal for that.

It's the easiest pedal to get the best classic sounds.

I have a 64'Fender Deluxe blackface with a 63'fender strat and 64'gibson SG, and I'm going bad cause I didn't find a pedal to overdrive the amp, without volume at 1 o'clock, until purchase OCD. This pedal is fantastic because with the amp at lower volume you can get amount of drive to figure the zeppellin sound. It's very quiet and the setting that I used is that Mike Fuller said in the fulltone's site: vol-10 o'clock; tone- 10 o'clock ; drive-3 o'clock. I have other Fulltone pedal to get the sound of Hendrix, like the '69, and some other pedals like TC's (Chorus/Flanger); Expandora-I; vintage RAT; Ibanez (TS9- CF5); BOSS (DD2- DC2) Cry Baby Dunlop (with Dan Torres Kit) MXR (Dyna Comp)

I loved this pedal and I really depend on it to use just OCD alive with my 64'deluxe.

I play some classic rock/Fusion like (Jeff Beck, Led Zeppellin, Jimi Hendrix, Eric Clapton, Eric Johnson, Mike Stern, Steve Morse, Scott Henderson, Living Colour, John McLaughlin, etc) and this pedal is very usefull to my arsenal.

The Fullton OCD is an extremely easy pedal to use. It has a knob for level and a knob for gain. It also has a switch to change between a high output type setting they claim to be more like a Marshall and a low setting they claim tobe more like a pushed Fender. I think they both sound Marshall(which is okay with me). It can be difficult to change batteries because you have to take the case apart. Otherwise it is a tank and extremely well built.

Fender Jazzmaster with seymour duncan pickups. Seymour duncan pickup booster, OCD, keeley loop bypass with a Boss DD-2, Ibanez CS-9, big Muff. Into a Vox AC 15 with an Eminence Red Fang speaker. Very quit and the true bypass works! I really like the sound. It's not a tube screamer type pedal which was what I was looking for. I'm not a tubescreamer fan, which makes the OCD a good alternative. I really like the sound. At lower levels it can be fuzzy but this pedal really shines when the amp is pushed to the top and the pedal adds a boost and drive that enhances the natural distortion of the power tubes. I find it works best with an older type aamp where the power tubes do the work especially an AC30 or 15 or even a marshall plexi. The sound is perfect for me. I'm giving it a 10 because it was exactly the sound I was looking for. Before I bought this pedal I tried all of Keeley's modded pedals and some other boutique pedals. But this one was the one.

It's built very solid. you can tell its made with quality parts.

Havn' had to deal with them.

I mainly just play a pop/ rock style. Everything from Sabbath to U2. I just wanted something that had a good overdriven sound. It mainly helps me get my Zeppelin fix out....no really I like this pedal, but as I said it was the right pedal for me. To me it's a completely unique overdrive pedal. I haven't really found anything else that sounds like it, but it was pricey.

Easy enough to use, however I had a great deal of difficulty controlling it. To much boost and too much overdrive for me to use.

Way over rated. I found it to be almost unusable (for me) with various Fender amps. Very, very buzzy at almost all settings. Loss of definition at higher levels. Didn't act at all like any amp I've ever used.

No comment. Very well constructed but I returned it within the 5 day return period. (Thank goodness for that!)

No dealings

I don't get the hype. I have a NAU Engineering "Spoonful Overdrive" that leaves the OCD for DEAD. The NAU OD costs $30 less and has a separate clean boost section built in. Call John Nau at 1-585-594-8129. Nau also make killer custom amps. I have been playing for almost 40 years and own lots of classic stuff including various Fender and Gibson amps and guitars along with NAU and Demeter amps.

Easy, almost plug n'play. HP, Lp switch. volumue, tone, and gain.
Almost too much head room on the volume. My only "complaint", if you wanna even call it that.

I consider this a distortion pedal. Fulltone doesn't seem to really clarify this. It doesn't really seem to work as an overdrive pedal to hit your amp's distortion with. But then again 99% of actual overdrive pedals don't work that well doing that either.

Telecaster into Ernieball vp jr volume, Boss trem, Barber Tone Press(bad ass comp), slammin on the OCD into the front end of a Bogner Shiva. Choralflange and DLS Echotap in the loop. Blends with ALL my fx wonderfully, especially the Tone Press. With the gain up full, and the tone press on, IT WILL SHRED. Not noisy at all, as far as hiss and squelch,feedback etc however I keep the volume at 9 o'clock in LP mode. Tis a LOUD little guy,as far as output at least in my setup.

As far as tone goes, IT IS NOT A TUBESCREAMER. No midrange bark. Wonderful high end. Tight bottom. I could go on and on and bore you, but to make it interesting my girlfriend said its sounds very "seductive". I've since renamed it "the panty-removing pedal".

Whether or not you like the tone may be up to one's own ears, but you CANNOT dispute the fact that IT does sound and FEEL like an tube amp REALLY COOKING!! I plugged this into a little multi-effect unit I use in my apartment for silent practicing, and WOW!! It really sounded like a wall of stacks. I could almost imagine the smell of the tubes frying. They're also not kidding about the dynamics. I personally don't get a Marshall vibe out of it thank goodness, but the Bogner's dist has that covered already, and that's why I got the OCD. I don't need two Marshally tones. If you have a Fender and your looking for chunk, this may be one of your best bets. I played this through a Deville in the store,and I picked it up that day.

I depend on it to remove panties.
What's a backup??

Mike Fuller can be a real meanie I've heard, but I'm guessing on the inside he's like a motherless child who just needs a big squishy hug.

I've been a gitar-picker for 16 years now, and I've owned many a od/distortion pedal over the years,all of which were traded,sold, ebayed or destroyed. If this were lost or stolen, I might get a new one, depending on how much I missed it. I give it a 9, being a really great keeper that I'm sure won't disappoint me, and inspires me to really beat the living crap out of my tele-blaster. I'm not so sure 10's really exist, but one can alway's keep looking!

You can Dial it in quick!

Not impressed with the overall tone of this pedal.
It's not organic or tube sounding at all. The gain is
tight. But too much.

Fulltone stuff is built!

Responds to email's, Good customer service.

I play Punk/Hard Rock. This pedal doesn't do it for me.
I've yet to try a Fulltone pedal that I really liked.
I'll stick with my Barber LTD & Modded DOD 308 pedal.
If this pedal had less gain I think I might really like it.
I would never buy this pedal again, in fact it's going back.
I have friends that use Fulltone pedals & they always have good tone.
Every time I plug into a Fulltone pedal I'm unsatisfied.

I purchased the OCD 1 year ago so I have had time to play with it extensively, ( this is not a 2 day honeymoon review.) The unit is easy enough to understand having the usual 3 knob layout, the only difference is the mini toggle switch located next to the bright blue LED. I keep this switch in the up (boosted) position at all times. It is easy enough to get good tone happening right away with the OCD, it doesn't do anything so extreme that it would muddy up the tone. It always sounds musical to me.

My review for the OCD is based on (at home) use only, I am not out gigging and trying to cut through a bassist and drummer. I do record at home but at lower volumes. I have in comparison several other pedals all of which I have had for quite some time. The line up includes an Xotic BB preamp, Xotic RC booster, Direct Drive, Barber LTD silver, Digitec Bad Monkey, Boss DS1 and OD3, Danelectro Fab overdrive. These are just the (mid) grind pedals, they all sound a little different and each has it's thing that it does. I am only 2 miles from Super Sound Music and guitar Center so I have had the opertunity to try out loads of stuff. Of all my pedals the OCD would most likely be the (one) I would keep if I was told I could only have One pedal and right now it is the only grind pedal on my board. It is very articulate and cleans up real well with just my guitars volume knob..I can go from clean to blues crunch to a singing type higher gain overdrive. The OCD has actually more grind than any of the other pedals listed above, this is a good thing. Pick attack is outstanding with this pedal and it responds just like a tube amp, like others have said it is just like an extention of the amp. The bass is tight and has great tone, not loose or flabby at all. Quality sound all the way through this pedal.

Very good build quality, has never let me down. Sturdy!

I play mostly rock but dabble in a little of everything. I have been playing 41 years and have had and or sold more stuff than most people will ever own. My main amp is a Genz Benz El'Diablo C30/60 combo (tube amp.) I would buy this pedal again as nothing else I have tried matches what the OCD can do. Through (my) amp this thing sounds and feels outstanding. Would I change anything about the OCD?.. well, I really like silent switching (for recording purposes) I really like the Digitec Bad Monkeys silent pedal switch and I guess I would lose the mini toggle as I only use the top position, there is too much of a volume loss in the down position. Still a quality great sounding piece. I'll be ordeing a Zen Drive very soon so we will see if the OCD can still stay on top. What are my qualifications for diong this review?..... 41 years guitar player and recording, have had songs reviewed in Recording magazine as well as being in Giitar Player Magazine 2005 (Spotlight on Talent) and 3 full length solo cd's in 2005. When it comes right down to it though.. it's your ears and your fingers and what you want to hear as to how the OCD will work for you. I like it.
