Seymour Duncan Twin Tube Classic

This is extremely easy to use. You dial up the sounds you want, and voila, it rocks.

This turns any clean channel on an amp into a powerhouse of three channels, all of which sound good (that is assuming your amp is decent in the first place)

The manual is basic. There's no need for a complicated manual, you have overall tone controls, which work well, along with volume and gain controls for each channel.

The sound quality is awesome. The rhythm channel is supersonically sweet. This has a nice low range to it (subject to using the tone controls). It fattens up my guitar sound perfectly. It seems to round it out into a more musical tone, on all pickups. My pickups are two Kinman 62s in neck/middle, and a Seymour JB humbucker in the bridge.

The lead channel is a heavy duty overdrive, good for most lead sounds. I've heard it described as 'buttery' - that seems to fit. It is round and smooth, and sweet sounding. Both channels are affected by the single tone control. This has annoyed me on amps in the past but is works really well on this pedal.

It is also very quiet in operation. One thing I have noticed is that it seems to make the reverb on my amp sound a bit sweeter- I have also had to turn the reverb down a bit, and it sounds great. I think this might just be that the tone hitting the amp is a bit fuller.

Here is the other BIG benefit of this pedal (apart from the sound).

Most compact time based pedals (delay/chorus/modulation) sound great in an effects loop. Most amp effects loops don't cater for standard pedal based signals, and it can be problematic using them in an effects loop. Also, running pedals like reverb or delay into a distorted amp can sound awful.

The Twin Tube Classic gives awesome tone, and is designed to go into the front end of an amp. This means that you can put your delay, and chorus/flange etc after the TTC and before the amp, with complete sonic compatibility. Running these effects between the TTC and a clean amp gives great results.

You can, of course keep things like fuzz/compressors/tubescreamers and wah in front of the TTC.

The TTC also really responds to picking strength and guitar volume settings with great dynamic punch and subtlety.

I give this a 10 as it has solved my effects routing problems, and left me happy. - but....

I have had to send this back to the supplier - it lasted a couple of days, and went fizzy and died.

This is going back to Imuso.co.uk today, and I should have a replacement in a couple of days.

I'm willing to assume that this is a one-off faulty product. There are not too many bad reviews for reliability here, so I'll give them the benefit of the doubt.

This was made in China, where I assume their manufacturing and quality control is as good as anywhere. I'd trust Seymour Duncan to get this right, so I'll stick with my assumption at the moment.

I'm not putting a low rating for this for this reason.

Never had any dealings with them. I've had a JB humbucker in my guitar for possibly 10 years now, and I assume it will still be rocking long after I'm dead.

I'll give this an 8 overall for all the good reasons I've listed.

This is an awesome pedal. I run the guitar into a Crybaby wah (completely gutted and rebuilt/modified by me) >> Ross compressor clone (I made this as well) >> Tubescreamer clone (Mine as well) >> Twin Tube Classic >> Line 6 Echo park (I couldn't make a delay that will do this) >> Boss CE-2 Chorus Clone (Yeah, I made it) >> MXR Phase 90 clone (Mine too) >> Tech21 Trademark 60 amp mostly on the clean/Fender channel now.

I've been playing more than 20 years and never had such a great tone as now with this pedal. The rhythm channel is worth the admission price with this one, the lead channel is an added bonus.

Could not be easier. Two channels, two footswitches. Attention, modellers addicts : you will have to practice the lost art of getting a sound without 24 amp models and 120 presets to go through. Within a half hour, you should have found the two sounds that you will add to your armoury. The dilemena is this : do you keep the rythme channel for a juicy tube clean sound, ou do you use its crunch potential ?

I use it with an Epiphone Les Paul with coil-splittable Di Marzios, an Ovation Deacon, and several other electrics. The sound is rich, very much 70s rock, but not Marshall like. I chose this over the H & K Tubeman, that I found harsh. It's sensitive to volume control manipulation, and splitting the humbuckers changes the sound like it should. Noise is really low.

Don't know. Did not take it to the gig yet.

It works, so no opinion.

I play mostly classic rock and hard rock (Led Zep, UFO, Sabbath) but also some Yes and poppier stuff. I like my clean sound warm and my distorsion fuzzy, with a humming low end, but with distinct pick attack. I have been playing for 15 years now, and have owned a dozen guitars and 3 amps. I think the sound is excellent, unless you like piercing treble ou scooped mids, that will not be available here. Better than a distorsion pedal, cheaper than a boutique preamp, truer than a modelling gizmo.

This pedal really is amazingly easy to use. It has good sounds all over but as it said in another of these reviews the tone knobs could use more breadth. They've made it so it can't sound bad but at the same time limited what it can sound like.

Sound is awesome. I read somewhere that you can use this to make your solid state sound like a tube amp.... it doesn't. Sounds better than any solid state ever could but plug this into a tube amp and the overall sound is magnificent. I play with a strat and a white falcon into a mesa subway blues and it is the closest thing to heaven on earth.
I tried this with friend's guitar that had p90s in it and it was really noisy. I think maybe the frequencies out of the pickups just didn't gel? But with either of the other two no complaints in the slightest with the sound.

Seems reliable, I think these tubes seem really good. As a pedal it's going to get kicked more than an amp so the fact the tubes are resistant to vibration (ie I accidentally dropped this while it was on. Hard)But don't like that you have to send it back when the tubes eventually need replacing.

no idea

I play all sorts of things and between the pedal and setting the amp up even a little dirty, the twin tube can sound like anything. It responds like a tube amp and I think that while amps can come and go this pedal will stay a consistent part of my rig. To say what's already been said a power switch would have been great but the pedal makes up for it in everything else. I've tried lots of transistor OD and distortion pedals but they've all sounded fake or just used them as a bit of a signal boost but this pedal is something beautiful and definitely worth getting. I'd get another if this were lost or stolen without a second thought. Have also used it to warm up mic'ed acoustic guitar, with the gain low sounds really nice, though with volume too much becomes a bit midrangey. Try one before any other OD/Distotion pedal.

Very basic, you have the same controls you would find on your amp.
Bass,Treble,and two channels with gain and volume control. The only thing thats missing is a Mid control. So it's very easy to get a great sound from it.

This has got to be one of the best distortion pedals around. It really just sounds like I added two great channels to my amp. I use it with my peavey penta half stack, and ultra tube. It sounds great through both. It's very warm, and is not really a heavey metal kind of distortion. Great for me since I play blues and classic rock. The first channel sounds like a marshall plexi turned up half way. The second channel sounds like you turned it up all the way. I use my EJ strat more than anything, and it really thickens up those single coil pickups. My les paul and firebird sound great with it too. It's almost just an extension of my amp, cause it doesn't color your amp too much. It warms it up and sustains for days.

It seems to be very well built. I've been using it for a few months now and have had no problems with it. And I use it every other day.
The only problems that I could think of happening is if something goes wrong with your wall wart your not gonna be able to use it.
Other than that it's built like a tank.

Never have dealt with seymour duncun, I own one of their pickups and it still works. I'm sure they have good reputation and want to keep it.

I have been playing for over 8 years now. I play blues and classic rock, and this is a great match for me. If it were stolen I would definetly get another one. I use my vox wah, and sometimes plug in my friends old boss flanger. They both sound great with this pedal.
I love the fact that it is very basic and easy to get a great sound from it. I looked into getting the tonebone,damage control,and vox, but this just seemed to be the best deal. If your looking for a pedal with great tube overdrive, you should look into the twin tube.

Actually is too easy to set up a good blues tone. The independent volume and gain controls for each channel gives a lot of flexibility. Anyway, as I am here not to make publicity, I see the following improvements points for the use of the Twin Tube :
- Include a mid control: The frequency range between 200Hz and 2Khz has no control, so you have to make mid correction with the amp mid.
- Include an ON /OFF key: Always when you need a brake you have to plug the SFX03 off from the wall, otherwise he will keep its working temperature (that is high!!) and therefore "burning" its useful life also under Bypass condition.

Here is all about expectations. I am a blues guitar player using a Gibson Lespaul Standard 59' with a Mesa Boogie Express and I just love the tone from this combination. My target by choosing an effect pedal was to add more flexibility with light distortion without loose my original tone... and the SFX03 gives exactly this. The first channel works as a boost keeping the amp warm and the second channel add the blues distortion. Before I got this preamp I did some research and comparison with other great pedals (BluesDriver, Bluesbreaker, Tubescreamer, Big Ben) and all those work very well but the problem is that they do not preserve the orignal tone. If you do not have a great tube amp or if you want to get only a "standardized" tone then maybe one of those can satisfy you.

My preamp is quite new so it is hard to talk about reliability. I have learned a lot about the 6021 tubes and , talking as an electrical engineer, I confirm that the useful life expected for those tubes is quite higher than a standard 12AX7. However I still have concerns because the tube garantee from Seymour Duncan is only 90 days.

No support was needed up to now.

As I said before, it is all about expectations. For a blues or a classic rock tone I do not see competition for the Twin Tube (maybe the V-twin from MESA if they decide to produce it again..).
If you are a "Seek and Destroy" kind of player I would recommend you to go to the transistored pedals.
Personally, I believe a great tone is defined by the guitar and by the amp. So I suggest you to search your musical identity (and spend your money) with the right guitar+amp combination. Only after find this identity than I totally recommend you to try the Twin tube ...

Its very easy to get a good sound from it, controls knobs shows in a logical format for the musician and being true there isnt any need of manual hints.

Its produce a variety of sounds, with the clear channel you can just "help" the signal of your low output pickup or you can get a mild distortion ... it produces those "british" sounds.

With the hi-gain channel you get a great amount of saturation / sustain but (incredible to say) without to loose too much "attack".
The distorted sound produced anyway is completely different from the one you can get on a 12AX7 based amplifier (Fender) its a sort of warm but hi-tech distortion ... I would say a '80 sound ... or an Allan Holdsworth like timbre.

Just for this is very nice when coupled with a Fender amp , since you can get a great variety of combinations.

I have to say (agains other reviews) that this unit its not noisy at all !!! I'am very satisfied ...and I'am using it in Italy coming from
a 230V 50Hz main voltage. I scale down with a transformer from 230V to 120V using a transformer. Clarely the frequency remains 50Hz since the unit is supplied in alternate current (16V AC)

I'am using it with a Fender "the Twin" (red knobs) amp upgraded with Electro Harmonix tubes.

I've had it for just one month ... it looks solid and I had no problem until now.

For sure I would use in a GIG.

Its weight lets you think it isnt "empty at all inside" ..

I had no occasions to deal with the company

I play prog-rock music its clean channel is a good match for this genre, the distorted channel is useful instead in two cases:
- When I want to get an hi-tech sound for other misical genres.
- When I jam out of my studio and I want a warm and reliable distortion with no troubles of presence etc..
I've been playing for 25 years and I own lots of gear including 13 instruments Guitars / Bass / steel guitars (Gibson, Martin, Epiphones, Rickenbacker etc..)
If they will stole it to me ..I'll buy another one.
I love its versatility and quality , the low noise .. everything.
I liked if it had the ON/OFF switch
I choosed this one over a Electro Harmonix Black Finger to lift up my guitar signal ... I choosed this one because more versatle and also because I read very good reviews of this. Also, I thought that being one of the Seymour Duncan top gear it couldnt be a dull object.

hook this up to your guitar and amp and just rock---it's just that simple.all my favorite guitarist live in this unit[it's more than a pedal].the sounds are sweet and buttery...and yes,up the gain and it can and does get nasty.tube heaven...............yes sir//

tube heaven.......if you can't afford a tube amp...just buy this...it's all you need.

solid as a brick.

i have purchased their p/ups for years.i have never needed customer support.

i play rock--blues..........this unit does it all.listen,i have owned and sold many pedals over the yrs.--this one's a keeper.thats right...10's all the way.......buy one and you will see.i went by the reviews on H.C.---i'm glad i did.i purchased this from A.M.S. without trying one out,thats not really a good thing to do,but in this case,it worked out very well for me.this is one of the best units you could possibly buy for yourself...it's worth every penny.

Very simple to use. One set of treble and bass master controls, Volume and gain on rhythm and boost.

I've had the twin tube for two weeks, here's my thoughts so far... the pedal has an excellent overall sound. The sustain is very sweet sounding at higher gain levels and feeds back well with humbuckers. So far i'm using it with a clapton strat and 57 goldtop. I ran the pedal in front of a blues jr. and threw on a couple of cd,s.. I was able to nail the "Venus Isle" lead tones of Eric johnson and "One more car/driver" tones of Clapton pretty easily. The twin tube will pretty much cover all of the Blues/Classic rock/Country tones territory. The controls are sensitive and interact well. I really wasn't able to get a bad sound regardless of where I set them. The jump from channel 1 to channel 2 is not a drastic volume or tonal change, like a tube factor, so the rhythm to lead switch is smoother. It;s also fairly quiet, quieter than both my soldano supercharger gto and tone bone classic...to my ears it also has a truer tone. The only negative I would note is it may be a little flabby on the low end to some. If you dig an overheated, saggy ,tweed sound like I do, the low end is fine. Don't buy it if you're a Metal guy, it doesn't do the scooped mid sound or Rectifier/Randall buzz saw. To my ears it slightly favors humbuckers. If your'e looking for an " all in one" gigging tube pedal that will cover most of the tones you'd want, try it out.. I highly recommend the pedal to fender tube amp lovers because you can set a great clean sound with the amp, a dirty rythym tone on channel 1, and a nice grind on channel two.. switching from single coils to humbucking guitars and working the volume knobs will cover almost anything from jazz to hard rock. very good pedal, However, I'm tired of reading 10,s on every review... so i'll give it an ...........

seems pretty sturdy and well built

I play classic rock and blues, This pedal is excellent for both. I would replace it if lost or stolen and think compared to both a tone bone and soldano, it's a better sounding pedal for those sounds

Super easy!

NONE BETTER! If you're looking for a OD that will give you classic 70's crunch look no further-this is THE pedal you want. I've got a lot of OD/distortion boxes including some of the best tube pedals out there(SIB Varidrive, H&K tubefactor, Tone Bone Hot British)also non tube( Bad Monkey, Barber DDSS, DGTM, Rumble mod, rust driver,Reeza, V-stack classic...) I've spent way too much money-but you don't have to! The Twin Tube makes all non tube pedals sound like,Well, pedals! This thing is really an amp in a box. If you want to NAIL the punch and dynamics of bands like AC/DC, Trower, Zep the twin tube will do it 100%. Some people have claimed that this pedal sounds muddy! It is not muddy if you turn the eq knobs.-Here's a good setting for starters that is not muddy-set the bass knob at 10 oclock and the treble at 3 oclock. It's amazing the sounds you can get out of pedals if you just turn the knobs! Spend $209.00 on this thing and don't look back! There is a reason this pedal is getting such high ratings-TONE!!! Like I said for 70's rock NONE BETTER! I play Gibson and Epiphone V's and this pedal actually makes my Epiphone sound great!

Built like a rock. Had it for 6 months no problem

Haven't needed it but if it's half the quality of this pedals tone no problem!

This the first time I've given a pedal a 10. Like I said this is the only pedal you'll need for 70's rock. Don't waste your money on no-tube boutique boxes-this is the real thing. But hey-I got some pedals for sale.....
Peace!

This is extremely simple to use, probably the simplest pedal you will ever own.

Natural tube sounds. Note that it doesn't emulate or model any particular amp and it has it's own sound. Probably not a great pedal for heavy metal, but it is great for blues and "classic rock". Some people have complained that it sounds muddy... My opinion after having it a few days is that it IS a little bottom heavy, especially if you keep the tone controls at equal settings. However, if you boost the treble a bit it evens out nicely. I would say the distortion tones are better than on my Tonelab as well as any non-tube pedal that I've ever owned or tried (yes, I've played a lot). Hvr, I have not had the chance to compare it to the Damage Control tube pedals, which seem like they might be cool as well.

Don't know, but the casing is heavy duty and it seems like it will last a long time. I am concerend that it uses special tubes, hopefully replacement will not be a problem.

?

I mostly play blues, been playing for about 30 years. A great match for my style.
