Maxon AD-900 Analog Delay

Time, Repeat, Level.

About as basic as an analog delay gets. The sweet spots on the Repeat knob for oscillation is very easy to find. Trim pots on the inside (I wouldnt recommend tweaking them much, if even at all. I did a little fine tuning to the decay of my signal for a bit of customization).

The best delay I've ever heard/played/owned. The tail of the echo is very smooth: the short repeats are clear and the longer they go on the more they turn into fading memories that massage themselves into your subconscious. A brilliant experience for any listener or musician.

I've never encountered an issue, and surprisingly it reacts very consistently with the change up of different amplifiers, guitars, and sound levels. I can always trust this amplifier to do what I say, like a well trained German shepherd.

n/a

Out of all of the pedals I've owned over the years (Klon, Matchless, Mutron, other Maxon, Ibanez, Fulltone etc etc) this is literally the only one that I kept. I sold all of my pedals off, even custom built ones. This one made it through debt, school, bands, girlfriends, jobs. I'll take this one to my grave.

Like falling off a log.

This is the two chip MN 3005 unit, which was a deliberate choice. I went looking for a clone for the Boss DM-2, (my favorite, which also has the MN 3005 chip) but with longer delay time. In my opinion, this is the unit. After much A/Bing the two, I sold my Boss DM-2. The Boss features 300ms of delay time; the Maxon has between 500 and 600ms. Sonically, they are incredibly similar (at least with my rig). I use two vintage Gretsches, one with Filtertrons and one with DeArmonds. I run them through a '63 Fender Bassman.

Seems very solid; no worries.

Maxon does answer questions on website quickly and thoroughly, although this thing is out of production, and out of warranty.

I bought this unit out of Japan on Ebay, fully intending to send it to Analogman for true bypass, and that is just what I did. It runs at 12 volts (more headroom), but I run a Voodoo lab PedalPower 2 Plus, so you only need to flip a switch to adjust for this. It is positive center on the power input jack, but you can get a tiny adapter for your power supply. It is larger than your average pedal, but I don't mind this. Supposedly, this cuts down on "cross talk," resulting in a quieter pedal. In my opinion, this is THE old school dark repeat delay pedal. It is exactly what I was looking for. Yes, I have A/Bed against the AD 999. They are VERY similar, with the 999 obviously winning out in the longer delay category. Tonally speaking, I think the 900 is better in the tone of the repeats, but I'd hate to have to live off the difference. I find it quite musical, and it does the analog delay thing better than any other (and I've tried quite a few).

as easy as it gets... typical 3 knob operation..time.mix..repeats

Recently ordered a used ad900 after buying a "true bypass" boutique delay..from one of the myriad of pedal builders claiming to have this art down..It was noisy...adding an airy hiss to my signal..And boosted the highend...and the overall volume...while sounding flappy and harsh...Simply not musical...
After all the glowing reviews on the ad900...and A killer price...I couldnt refuse..
Whether through my clubman 35...Dr. Z kt45...Orange Rockerverb..or the fender amps...it soesnt matter...Absolutely no tone coloration at all...Absolutely no noise all at...Warm fat..haunting echoes...
Simply perfect...I'm starting to question the true bypass craze...When some of them are clearly coloring your tone...And there's no loud pop either...
I can get all the sounds I need....

just got it...but it's used...and works perfectly...
I've never had issue with any maxon pedal..so..

never needed em

tested against many others....They are all going up for sale....
The only complaint is: 12v vs 9v.... Needs a seperate adapter with certain power supply units...

As everyone says, three knobs and no surprises there.

Dark. Degrades. It's analog. You won't get chimey sounds out of this nor well-defined high-gain palm mutes. It's a very warm, musical sound that will make your lead and solo tones a mile deep. For rhythm work I just use a few quiet repeats to fatten things up, the decaying repeats provide a lovely rich grumble to support any higher-register voice leading in the chords.I use it exclusively in the FX loop of my Mesa Rectifier Preamp into a Mesa 20/20 power amp and a pair of Avatar 1x12 cabs. My main axe is a super-versatile Yamaha Image Custom.

A really upper-mid-heavy, snarly higher-gain tone really cuts through the repeats, sometimes to the point you barely hear them anymore. Conversely, a big fat dark tone will make for very muddy sounds as the repeats decay. These are the limits-- however, they can make for versatile effects once you figure them out.

It really does have its own sound-- it's virtually an instrument unto itself. This can be good or bad, depending on how you look at it.

I don't notice any tone suckage, though my preamp's fx loop does not do 100 per cent wet mix so that may be why.

I generally play post-heavy (Sigur Ros down through Mogwai to Isis, Pelican, and some stoner stuff.)

So far it's dependable, I've jammed with it a fair bit. It seems solid.

No opinion.

It's definitely a limited effect for the price and compared to digital boxes; you have to be wanting to make this part of your sound. I've got a pretty big gear budget, so I would probably buy another if it wandered away, or maybe I'd look into the AD-999.

If you use a lot of delay and can only justify one delay unit, this probably isn't it unless you're an analog cultist like me. I'm very happy with it but I can see where a lot of people wouldn't be.

Simplicity. Three knobs, Delay Time, Repeat and Delay Level.
There is one but you don't need it.

Perfect smooth analog delay. The quality of each echo deteriates just like a tape loop.
Unlike my BOSS DD3 the delay is very musical and in no way harsh even if you did in to your guitar.
I use it with a Two Rock Jet, in-line.

Very high build quality. Should last for years.

Don't know.

I play blues and use the MAXON for a slap back echo a la Robben Ford.
It really fattens up the tone and give a spacious sound.
Best delay I have tried so far. I was going to invest in a Fulltone tape echo but I am very happy with this unit and it is maintenace free. Only problem is it is a bit pricey, but this is probably due to the custom chips which are used.
Great pedal.

No markings around knobs to reset favorite settings. Otherwise easy.

Analog delay. Thats what it sounds like. Analog delay. Nice though. Repeats degrade nicely and noise slowly becomes prominent on longer delays. Thick but spacial.

Ive got a strat - 59 tweed princeton - strobostomp - ts9 original (but with the "bad chip" hahahaha) -tonebone british - ad900- catalinbread semaphore

PS Yep- sucks tone. Sorry. Use it in the loop. Notice- still a 10 rating. Just sounds great. Have analog man mod it for REAL TRUE BYPASS. That was some Maxon BS!!!!

Bought it from Japan. 2 chip version. I didn't even look at the ad999- headroom is VERY important people!!! Bottom line- I love it!

Tank. Bigger than it needs to be though. Great quiet switch. I have NO worries!

dont know.

The reviews here are for the most part right on- great sounding but a touch "pink floyd-ish". Dark and degrading. YES slight ringing overtone at times. BUT all of it is very musical. I didn't chance it and got the 2 chip Japanese version- MAINLY because Japanese companies LOVE to keep the quality a little higher at home. It may not sound different than the 4 chip but I wouldn't be suprised if it did!!! It makes me VERY suspicious when the Maxon website addresses this issue so better safe than sorry. Bottom line- Worth every penny.

So easy 3 knobs

Dont believe any negatives this is the best delay out there ..100%

Not caved in yet

Never used them

This is the business , I would say it is in a class of its own , if a Fulltone TTE or a WEM Valve copycat could transform into a box this size , I would choose them , but as they cannot this is the only choice for me , and I am the tone master , I would notice the difference if you changed you strings 10 minutes ago ,and 20 minutes ago !!!!!!!!!!!!!!!!!

I'm taking a point off for the AD-900 needing its own adapter.

There is a slight metallic ring accompanying the original note and repeats in some cases. Overall, the pedal sounds great, but it is not as "smooth" as my rack-mount Ibanez AD202, which sounds equally "organic."

I AB'd the AD-900 and AD-999 for two hours. See the details in the "Ovarall Rating" section.

It seems that a lot has been written about how the Maxon AD-900 is far superior to the Maxon AD-999. Well, I just had to hear for myself. I bought one of each, and I AB?d them for about two hours. I set them up with a multi-loop true bypass box so that I could switch between pedals almost instantaneously.

First let me say that both the AD-900 and AD-999 sound great. I used to have an Ibanez AD9 reissue, and that pedal isn?t even in the same ballpark as the Maxons as far as tone goes. Of course the AD9 was a lot cheaper. Anyway, although both of the Maxons sound great, I do still prefer the sound of my vintage Ibanez AD202 rack-mount unit to both of them. Of course, pedals are a hell of a lot more convenient than my rack-mount unit, so I won?t compare the Maxons to it. I will note, however, that the Maxons both have longer delay times than the AD202 and other vintage rack-mount analog delays, so even if you don?t mind using rack units, you might still want to check out the AD-900 and AD-999.

Okay, so which pedal is better, the AD-900 or the AD-999? My conclusion is that neither pedal is better. The AD-900 is better in some ways, and the AD-999 is better in others. I will describe the advantages and disadvantages of each pedal below. In summary, however, the AD-999 seems to be the better choice overall for my purposes. That?s right? I AB?s them for two hours, and I?m keeping the AD-999. While the AD-900 may be better for some people?s purposes, I really think that it is a bit over-hyped. If you ask me, even the AD-999 is overpriced, and the AD-900 is drastically overpriced. In my opinion, I would say that most people who are thinking about getting one of these pedals should go with the AD-999 unless cost is really no object, in which case a fraction of guitarists might find the AD-900 to be a better suit their tastes. Of course, if you don?t mind incurring some transaction costs, AB them for yourself! Now on with the details?

News flash: The AD-900 sucks tone!!! I was really surprised how much sparkle the AD-900 cut out of my signal. It didn?t even matter if it was on or off. Don?t get me wrong; it didn?t drastically degrade my guitar?s tone. However, you?d think a pedal that costs this much would preserve a little bit more of your signal in its ?natural state.? I really didn?t believe it at first, so I even reversed the position of the two pedals to make sure that it wasn?t my bypass box that was messing things up. It wasn?t. The AD-900 dulled the tone of my Fat Strat running into my Traynor YCV40WR even when it was turned off. The AD-999 did NOT have this problem. The benefit of the AD-999?s true-bypass switching seems to be more than hype, and the AD-999 transparently passes through the dry signal when it is on, as well.

The biggest advantage of the AD-900 is in the tone of the very first repeat. It is very hard to explain. The first repeat from the AD-900 is just a little bit ?truer? to the played note than the first repeat from the AD-999. ?Warm? and ?dark? are pretty vague terms, and sometimes they seem to be used as synonyms when people talk about delay pedals, but to my ears, the first repeat from the AD-900 is slightly warmer and ?sweeter? than the one from the AD-999, which is darker. This difference, however, was not noticeable to me beyond the very first repeat. Also, the difference was only obvious when delay times got fairly long --- above three tenths of a second or so.

Close your eyes and use your ears. 3 knobs. - lots of good delay sounds

Fantastic!!! I also own the way huge aqua puss which is also a fantastic delay pedal. Its very hard to say which one is best. The ad900 is a strat and the aqau puss a les paul - both fantastic.
Mine is the rare 2 chip MN3005.
Mine is not noisy at all. I'm using it with diezel amps. Top sound!

no problems yet

no problems yet

Super delay pedal. I use to own the Ibanez ad80 which is also a great analog delay pedal. But since I bought this along with the aqua puss - i don't need any other delay pedals

three knobs to turn- very straight forward.

Sounds wonderful. I've run it in every possible position in my effects chain, including after
a sizable clean gain boost. It has terrific headroom. If you turn the delay time knob while
holding a note, it creates these wild pitch bending sounds. The other guitar player in my
band has one too, so we have taken to turning the other person's delay time knob in the
middle of a song. It's just too fun.

I use an egnater tol 100 combo- ad 900-keeley compressor-chicago iron octavian.
All the delays I've tried since buying the maxon come up considerably short. I tried
the lower priced maxons as well. In my experience, they weren't nearly as good as the
ad-900.

Tape echo has a great sound, but it costs more than the maxon, not to mention that
tape wear is inevitable and has moving parts that will eventually wear as well.

mine has been dropped, spilled on and stomped by my cruddy shoes. I even smashed one of
the knobs off (whoops). It still works perfectly.

It does have a unique 12v adaptor that could go, having fried several 9v adaptors by
plugging into a clubs dirty power. One night, a surge killed all of my adaptors except the
maxon. I prefer batteries for this reason, but the maxon hasn't let me down.

never needed em'

I hate to give out a bunch of perfect scores, but I really think this thing is at the top of the
heap. I guess if you're into really long delay times, you might search elsewhere, but that
wouldn't interest me. If it were stolen, I would surely look for it's purple-pink face with
only two knobs. Buy a new one? Don't ask- all these toys have already cost me more than
my car. (1989 camry)

This pedal is very easy to use. 3 knob setup like other analog delays. It uses a 12 volt adapter which gives it more headroom, but you can still power this baby with Pedal Power 2 if you want. Just use one of the ACA outlets and set it for 12 volts. Then, you need to get a reverse polarity cable from Digital Music Corp. The AD900 is center-tip positive, hence the special cable. Digital Music sent me 2 or 3 for free. So no more bitching on this site about having to use the wallwart...you don't! I power mine this way...no problems!

Sound quality is excellent. I also have an AD80 and I prefer that for shorter delay times because it's easier to fine tune the delay time. the AD900 has more headroom and is probably a bit smoother. Pretty tough to beat this pedal for tone quality.

This thing is well built, but out of production...makes me nervous every time I take it somewhere!

Talked to them once about some clock noise I was getting from the AD80. They pretty much referred me to Analogman whom in turn referred me to Howard Davis in NYC. Once a pedal is out of production it seems like you are SOL. It's almost as if they weren't responsible for the AD80 anymore. So God forbid if my AD900 acts up...

I play all styles and this pedal is really good. It has more headroom than most any other delay that I know of and really outperforms them at stage level volumes. Anything can sound good in your bedroom...it's when you get it on the gig that you find out the truth...the AD900 delivers the goods...highly recommended!

twiddle the knobs until you are pleased with the sound.

I have to chime in on "anonymous's" comments below, he raises some interesting points....I own and use both the AD-9 and the ad-900 in my rig.....i think they are both excellent delay's. I have gone through a multitude of delays over the last few years chasing tones, searching for ease of use and feel I can speak from some experience. I also have been playing for 25+ years and currently play out regulary in a classic rock/GB band. I've used every digital/analog delay out there..recently bought and sold the Ibanez ad9 ( distorted too easily, not sweet sounding ). I've had the Yamaha UD stomp,rack units, the line 6 dl4 you name it...but I always come back to the warmth of analog and the wonderful sound of these two pedals. I tried the ad 999 as well.....but returned it. I just did'nt like it. It just distorts much to easily and had a fuzzy sound and does not have the warmth and clarity of the ad 900 and ad 9. Maybe the newer chips aren't as sweet or something.

In my rig I set the ad 900 for longer delays and the ad9 for shorter slapback sounds. I agree that the volume drop is a non issue on the ad 9..........it's so negligible that it's just not a problem at all in my opinion....i feel that there's more of a volume drop with the line 6 dl4 than with the ad9. If your sitting in your bedroom every night with your ear next to the speaker you may notice it...but trust me it's a non issue, very, very neglibible. Also the shutter effect on the on/off switch on the ad9 is alleviated by just stomping quickly....non issue as well. Where I completely disagree with the review below is relative to the sound quality of the ad 900....If i had to choose just one delay to take to a gig it would be the ad900 not the ad9.....overall it's a better sounding delay.....for one simple reason, the increased headroom provided by the use of 12volts rather than the 9 volts used in the ad 9. It's clearer to my ears,can handle hot pickups and strong distort boxes or loud compressors better, it's warmer and more intangibly musical, and more versitile because of the longer delay times. And the switching is flawless and smooth........now of course there are many varibles...guitar, amp, other pedals, your ears..........belive me I love the ad9, it sounds great for analog delay up to 300ml.....it's warm, clear and articulate for an analog chip..........but the ad 900 is just a bit better in all categories......perhaps the person below got a bum ad 900 or something. And for the record I dont play nor do I want to play any pink floyd tunes.......that's not the sound I'm going for.....

Also for the record I use american deluxe strats with SCN pickups and a gibson johnny a signature hollowbody into a mesa lonestar with other high end "boutique" effects and all George L cables.

Maxon has a great track record ( except perhaps for the one the person bought below ).

No worries

..........you just can't wrong if you looking to bask in the warm glow and haunting, analog ambiance of this brilliant sounding delay......if i could have only one effect on a desert island...this ad 900 would certainley be the one....

Pretty easy to get a decent sound out of it. Annoying to have to plug in a special 12-volt AC adaptor. Very smooth, no volume drops or switching noise.

Used with Gibson Les Paul Standard into high-end Crate tube amp. With other Maxon effects.

Hate to say it, but I have to disagree. I got an AD-900 thinking that it was the be-all-end-all of analog delay. It was too dark for me. Maybe somebody messed with the trim pots; wasn't me. It was very natural, very transparent, and I guess in a sense that was what I disliked about it...it was muddy because I couldn't hear the difference between the original signal and the repeats. Maybe that's what you're after. It was too Pink Floyd sounding for me.

So I got an AD-9 instead. Bingo! Winner. Much brighter, and very easy to distinguish the repeats AS repeats. Therefore, much clearer. The AD-9 has almost a sparkle to it, a 3D-ness and a life that that AD-900 didn't, especially when cranked up to 300ms.

The AD-900 is not bad, but it's missing something. If you want Pink Floyd sounds, get this. If you want something more versatile, get the AD-9. Yes, the AD-900 has twice the delay time, but I think that the tonal palette it has limits the range of songs you can use it on. Maybe that's just me. I was initially scared off of the AD-9 by a review complaining about volume loss and a shutter effect, but those turned out to be non-issues for me.

Got it used, trusted it fine.

Kevin at Godlyke RULES!!!!

He RULES!!!!!

Any questions? He RULES!!!!

Maybe I wasn't clear the first time.

He RULES!!!!

Enh. Too dull sounding for an analog delay. 301-600ms range wasn't even useful to my music (rock and metal.) If you get one, floyd-head, put it in the effects loop. It will sound SO much better. Running it in front of distortion is a mistake. In the end, I didn't keep it. Maybe this is what you're looking for. But sometimes, I think, there's such a thing as "too transparent", where your effects work against you because it's hard to distinguish the processing. They are doing SOMETHING, right? They are EFFECTS, right? In the end, we're only pleasing ourselves...my wife (whom I love dearly) can't tell the difference between a wah and a chorus. I like my effects natural, but to sound like something.

Easy

See Jason on 5/5/04 - I couldn't say it better than that - absolutely amazing warmth and beauty, almost subconscious in it's effect. I tried to replicate it with a deluxe memory man - sounding great - but always sounded like an 'effect' - the ad900 melts into your tone, becoming one with it. it's absolutely beautiful. I've tried a tube maestro echoplex - the best ones - which sound phenomenal also, but the maxon gives is just a different sound. my 4 perfect delays for differnent days - maxon ad900, echoplex, deluxe memory man, a good digital delay for what you can't get with analog!

been working great for awhile on my pedalboard

never had to deal

Magnificent

3 knobs, two hands, whats the deal?

Maxon obviously 'voiced' this pedal for a fat, warm sound. I happend to like that! Very transparent when dialed in correctly, super quiet, flawless! Adds a 'haunting' spacial effect to my Fender's reverb, very cool! Very musical and worth every penny (note: you have to know how to use a delay pedal, though)

Over one year of constant use and no worries...

Don't know....Don't speak Japanese....

I have been playing for over 33 years and have used it all...(echoplexes (solid state and tube), Chandler delays, tons of digital delays, Line 6 delays, MXR analog delay, DOD analog delays etc....for me, this pedal is the best of my experience.

Very easy and simple. It will oscillate if you ask politely but not as easily or fast as my vintage AD-80.

No noise at all, no loss of tone, very very transparent and switching is as smooth as butter. Which makes this unit a dream to use, if only all my pedals were as well engineered as this one.

The sound is very organic, rich and buttery. It is also very clean and unobstrusive(my original AD-80 will distort a bit which brings an interesting vintage vibe.)

It does sound beautiful but is a tad darker than my AD-80 or any other delay I own. This loss of highs is often very nice and cozy but for some application I miss definition wich interfer with my playing. This is what some people call muddiness I guess.

If you play with a warm sounding guitar into a bright sounding amp, this pedal will sound like heaven. If you do the opposite, you might get frustrated with the loss in the high frequencies. Try before you buy unless you know exactly what you are buying.... especially at the price it is today.

Oh..and by the way, this pedal souds TERRIFIC direct into the board.

This will not be my one and only delay. When I need a warm analog and close to tape delay sound, especially going higher than 300ms this is definitely the top of the pile. However when I use lots of repeats or have to get a twangy slapback kind of sound I pick the AD-80 (AD-9 would be fine I guess). For more modern sounds requiring clarity, I will rely on something else.

Classic 3 knob configuration: Delay time, Repeat, Delay level. Obviously a piece of cake to use.

Four original, no longer-in-prodution Panasonic MN3008 bucket brigade chips are the brains of this unit, allowing you to dial in anywhere from 40ms to 600ms of the absolute warmest, smoothest, most creamy and dreamy sounding analog delay that your unbelievably lucky ears will EVER have the ultimate pleasure of hearing. The repeats from this little gem fall from heaven like a warm analog rain that you just want to stay under forever and get drenched in. This is positively without a doubt the delay of the gods.

Built to last. I'm sure that it will be around for someone else to steal after I am dead.

They answered all of my questions. No problems here.

The AD900 totally destroys every other type of delay, be it analog or digital, that I have ever heard in my 20-plus years of playing electric guitar. Nothing else comes close in terms of pure, rich, organic, mind blowing sound. To me it represents the absolute zenith of tone. I bow in reverence to Maxon for creating the only thing I know of in this life that is truly PERFECT. Yes, it seems expensive until you realize that perfection can never be achieved cheaply. Ultimately, price is meaningless. Just pay it and live happily ever after. Nuff said.

Really easy to use and get a great sound. Three knobs: delay, repeats, and level. The manual is pretty good in that it does make some suggestions as to how to dial it in. Really not neccesary, though, because it is a pretty simple pedal. 600ms. delay time, which is really long for an analog pedal. Definitely adds to the AD900's versitility.

As far as analog sound quality goes, this thing is sweet! Nice delays that are warm, organic, and natural sounding. I've never been happy with any delay before, but this one really changed my opinion! I use this pedal at the end of this chain: Various Guitars-> Keeley TS9->Keeley Comp->Mojo Vibe-> AD900-> Various Amps. Sounds great with anything I've paired it up with. Highly recommended!!!

Seems dependable, though you never know. Runs on the 12V adaptor, so I guess if that were ever lost or broken, it could be difficult to find a replacement.

Haven't ever dealt with Godlyke, or the Japanese distributor. I bought this from Larry at Soulcactus Sound in Arizona, and he's always been good to me.

I play music that ranges from the blues to rock, and this pedal is a great compliment for these genres. If this pedal were stolen, I'd be pretty heartbroken, considering their price and their limited availablity. I really like the warm delays this pedal adds to my sound; compared to digital, well, I don't think there is a comparison here. One last thing, these are expensive, but you get what you pay for and your ears will thank you.

Three knobs. A no-brainer

I play an ESP Strat copy, a Fender Rhodes and a violin through this and other quality effects into a Twin or into the house PA. Sounds superbly warm and organic. I guess part of the analog thing is that there is a degree of hiss added to the repeated notes, audible when the level of delay in relation to your signal is very high. I back off the treble and it becomes part of the organic-ness of the sound. Pink Floyd is in there. The Edge is in there. I'm in there.

No trouble at all. Relies on a 12v adapter.

Godlyke Distributing answered my email promptly and courteously. I hope my pedal doesn't break as I understand the Panasonic chips are scarce.

OK- here's the reason I wanted to chime in- Godlyke, Maxon's American distributor asks for $450 for a new AD-900. MusicToyz sells it for $399.95. If you look hard enough on e-bay, someone will eventually offer it for $290, shipped "direct from Japan". That's how I aquired my little darling. It arrived with a Japanese manual and an invoice from Ishibashi Music in Tokyo. I went on their website, ishibashi-music.com just to see how much they are willing to part with it for. ASTOUNDING! 23,040 Yen which translates into $193.88 by today's exchange rate. $214.88 with shipping to the US. Now, there's a lot of hype about the AD-900 and I think it's well deserved. It sounds gorgeous and has the second longest delay time of any analog delay pedal I know of (600ms beaten out by the 800ms of the Moogerfooger MF104). But I think that the mark-up rate is absurd and it's a shame that a few greedy people are putting this pedal beyond the reach of most players. Unlike the Moogerfooger and the Aqua-Puss, the AD-900 is still being produced and can be had for up to half what people are asking for, with just a tiny bit of research on the buyer's part. If you are thinking about getting it, by all means DO! But get it at a fair price and send me the difference.

This pedal is very easy to use. Typical three-knob setup like most other analog delays. Uses a 12v adapter. The manual offers some basic settings but you really don't need it.

The sound quality is superb. The best sounding delay out there right now. I've used it live and in sessions. No noise whatsoever. Maybe the previous reviewer had a lemon or something. I can't see how you couldn't get a great sound out of this unit. The delay is warm and fat. The Dan-Echo is okay but doesn't come close.

I've never had a problem after about 6 months of regular use. It seems very well built.

I've never had to deal with them.

I do agree that this pedal is too expensive. I would recommend the Maxon AD80 or the Dan-Echo if you're on a budget. But if you want a REAL analog pedal this is it. The Dan-Echo is digital with a hi-cut knob that "simulates" an analog sound. Cheaper, yes, but it doesn't sound as good. The Maxon is the real deal, baby. This pedal won a pick award from Guitar Player magazine because of its tone and 600 ms delay time. I think that $200-250 would be a more reasonable price.

There is no GOOD sound in it. Very easy to find a mediocre one.

Sound is very generic and not particularly quiet. Using in the effects loop with a Rivera Suprema amp. Guitars mainly Tom Anderson Classic, Fender Custom Shop Strat, Hamer Special. The Dan Echo at a third of the price is a much more realistic and pleasant sounding analog type delay.

Probably dependable. There aren't any moving parts.

Eric Johnson type Rock. The usual assortment of Hendrix , Gary Moore, Satriani etc. Been playing 40yrs(started very young). I have a few delays,Lexicon , Rocktron, Roland, Dan Echo. This is the Worst. Terrible value for the money.

simple intuitive layout. every setting sounds cool. like with any effect all you have to do is come up with the right setting to apply to the right guitar part.

sound quality is superb. you can't hear when you kick it in or out. perfectly seamless. very quiet. definitely warms up your tone, but in a great way. very different type of delay than a digital delay, and has it's own application. IMHO this pedal is hands down the best analog delay out there.

construction is top notch. i also use a maxon PT999 phaser which is also flawlessly built. never had a problem for a couple of years now.

analog delay in general sound sweet to me. but this maxon pedal just sounds great and is a notch above the others out there. i also own a digital delay for variation and for a wholely different effect. the pedal has ample amounts of memory or whatever you want to call it. which gives you that amazing spaced out sounds. but it really can cover the spectrum from slapback to spacey incredibly well. very toneful. if you gotz the cash and you luvz the sound of analog delay -- this be the one for you.

Very easy to use. Just as easy as any other delay I've used.

Absolutely the best Delay I have ever used! Period. I've owned a ton of Ibanez, Maxon, etc. High end, low end you name it and after selling one of the original 2 chip models, I purchased a newer 4 chip model. It is the same beatiful organic deep delay I remembered. The AD 80, which I used in between the AD 900 is great, especially if you don't have an extra $100 laying around but the AD 900 IS IT!

Should last, like all the other Maxon stuff I have owned.

Never dealt with them so I can't say either way?

If you want the most organic, longest delays possible get one. If your on a budget, get a Dan-Echo. In between get a AD 80.

Easy to get a good sound, a little harder to get a particular sound that you are looking for. I guess you just need to play with it for a while and get used to it. As simple as any other delay pedal. Sometimes it's hard to hear exactly what's changing when adjusting the knobs without turning the delay level way up first, then turning down to the level you want. This is what I like about it though, it's kind of organic that way...

I use a SG copy with Barden Humbuckers into various effects into a Marshall DSL100 (I only use the clean "plexi" channel). I use this in line and haven't tried it through the effects loop since it sounds so good in line and I don't want to run 2 extra wires to my pedalboard for 1 effect. This thing sounds so clean (for analog) and natural. It is definitly fat. You can get almost a reverb sound from it if you adjust it right. I have a tube reverb on the amp and this pedal sounds just as good (a little different, but just as fat). This pedal is very transparant with your tone. It doesn't mess with it. You can't hear this pedal turn on like some pedals, it kinda blends right in. I love it!

It seems tough, I just got it though so who knows... Definitly not cheap feeling. I trust it will hold up and I don't have a backup since I don't use a delay all the time. I could finish a gig without it.

Never dealt with them, they make awesome products though...

I play psychedelic jazz, blues, rock, bluegrass. If you want a fat delay, this one is great. I wouldn't go as far as saying that Digital Delays suck. They have a time and place for them and there is a time and place for this delay. There are some nice effects you can't get with this delay that you can with a Digital Delay, and of course, vice versa. I personally prefer the analog for most of my applications, and I don't think I'll ever buy another delay unless I lose this one or it breaks. This pedal is definitly over-priced, but I have this habit of buying what I feel sounds best no matter the price (within reason). Also, I hardly ever will use more than 300ms with this, so if your shopping around, you may want to get an AD80 which is usually a little more than half the price of this bad boy and will sound very close to the same (if your input is not too hot!) I must give it an 8 for the price.

The thing is easy to use. The last knob is the most important - Delay Level. I set this so the subsequent echos are softer than the initial note/s and fade out so there is no anoying overlap. Very Nice.

I'm using a 1970 ES335 and a Carvin DC 200 into a Hughs & Kettner Tube edition 20 watt amp. I use use different pedals at different time; Big Muff, MRX Envelope filter, Fultone Distortion Plus and Fat Boost, Maxon compression, Boss GT-6, etc. I found that the delay cause the distortion chanel of the amp to sound weird and broken up so I decided to try putting it through the effects loop and man, is sounds SWEET!! Warm, rich, and Phat. Like honey. It does tend to take the volume down just slightly and evens out the notes a bit (a little compression?) when it's on, but overall, definitely worth the money. I don't know what I would have done, though, without a effects loop. So keep that in mind.

It seems quite sturdy and too expensive to have a back up so I'll use a Boss RV-3 if it goes down - but there's NO comparison between the two. I only hope the latter never gets used.

I hope I never have to find out.

Running through the effects loop I don't think anything could sound better. Too bad they are sooo expensive because everyone should be able to use one if they're into delay.
