Electro-Harmonix Double Muff

At first, you see 3 knobs and say "how hard could it be to use?" as a matter of fact it takes a fair amount of time and experimentation to dial in the tone you're looking for.

i dock this device a lot of points for not having a footswtichable selector for the single-double muff option. there is a HUGE difference between the two and the little knob is not stage-friendly at all as is.

my set-up is simple: Reverend Charger 290 (2xp-90 pickups) -> Double-Muff -> Wah -> tuner -> an epi valve jr (or sometimes software amp simulators.) occasionally i throw a small stone phaser or small clone chorus in the mix as well.

keep in mind the following: this IS NOT A BIG MUFF PI. period. if you want smashing pumpkins-style walls of fuzz, this will not do that. end of story.

SINGLE MUFF: fat, warm overdrive. with knob all the way turned up, you get this crunchy, broken-up kind of tone that's not over top at all, but is quite meaty and harmonically rich. exactly what an overdrive should be.

DOUBLE MUFF: this is the money channel. the "gain" if you will is controlled by the top knob. from left to right, you get more of a crunch tone to a full out "hairy" squealing buzz.

there's a kicker: the single muff knob down below. it is a billed as a sort of "volume control" for the double-muff channel, but that's only partially true IMO. it also acts as a mid-cut/mid-boost, and here is where a lot of the magic happens.

by adding/subtracting mids, you can take a "buzz" type of sound and flesh it out into this hybridized fuzz-overdrive that is thick, violent, and wonderfully harmonic for both rhythm and lead work.

my favorite setting is with the top (double muff) knob about 75% up and the bottom knob just shy of halfway up. i would buy the pedal for this one tone alone.

ALSO: both settings are exceptionally touch and volume sensitive. roll back on the guitar volume just a touch, and you get this fantastic clean-crunch sound, a lot like the Kinks or something.

i would recommend for: all yardbirds/jeff beck enthusiasts (and all heavy blues lovers generally), fans of The MC5 (in fact all punk guitarists should take a long look at this), cream, robert quine/matthew sweet ... also great for pearl jam, aerosmith, stone temple pilots, deep purple styles ... you know, hard rock but not "modern" metal.

i wouldn't worry about it at all.

Never had to deal with them.

I love this pedal. I can take an overdrive and push it into higher-gain stages with tremendous precision. it adds thickness and richness to my tone without ever drowning out the "guitar" in it. it's great for feedback.

The lack of a footswitch for the single muff-double muff channels is a big problem, especially since you can use one as a rhythm and one as a lead setting, if you want. That needs to be addressed big-time.

A great buy for virtually any musician.

It does demand to be first, but recently i bought and mxr phase 90 and discovered that it can go behind that. Adding this info to the reviews here is the primary reason i'm writing this review. Plug the TU2 in though either side of the phase 90, and it's a no-go.

as stated below, a footswitch would be nice to go between single and double. other than that it's a piece of cake.

the seven is primarily because it's difficult to put anything before it

working the volume knob on the guitar is the key.

well, the single muff know on mine doesn't work- it's all or nothing. And i take pretty good care of it.

i've thought about replacing it with the micro muff ( or do they call it the mini muff)because i almost never use the double muff mode anyway and it would take up a lot less room on the board. but i'm not sure if it would sound the same, despite eh's claims that the circuit is the same.

As previously stated it has 2 knobs and a switch. The switch selects single or double muff. The knobs are pre and post gain. Very easy to use, and you can get a great sound as long as long as you acknowledge that this pedal has a personality disorder, and demands to be first in your signal chain.

Sounds fantastic, though it would be more versatile with a tone knob. On single muff it is a simple overdrive that will push your tube amp into gain. On double muff it will begin to come closer to a distortion pedal, but never becomes "sharp or harsh" but rather sounds more like an extreme overdrive. Its definately nothing like my Big Muff (not a fuzz). It does have some minor hum, but nothing unbareable, and certainly better than a Big Muff.

It is an all around good "classic" sounding pedal. Though, it must be noted this pedal is an EGO-MANIAC, and will act out if it is not first in your pedal chain. If you put any pedal infront of it it will buzz and hum, the overdrive will become grating sharp and noisy (not useable for any genre I could imagine). This makes using any type of envelope filters impossible, because they can not work after a distortion. Remember to respect it's nature and you will love the sound.

Never had a problem yet with an EH.

Never had a reason to call.

I play rock, blues and reggae. Its definately great for blues and rock on double, and works for reggae on single. Been playing for more than a decade. I would say it gets alot of classic sounds, and a few unique as well, I enjoy this pedal but have problems with it's need to be first in the signal chain. If lost or stolen I would stick with my tube-screamer, as that covers most of the Double Muff's territory and has a tone knob. I would recommend that you try it in your rig before you buy it- as stated multiple times -It has a personality disorder, and doesnt get along with others.

Others have described the basic features, so I won't go into much detail. One wish I have would be that the "single"/"double" switch be a footswitch instead of a little toggle. That would make the pedal more versatile for performing. But the two knobs interact similarly to the way the two gain knobs worked on old Boogie amps. Not difficult to get good sounds from it.

The only negative on ease-of-use relates to signal-chain issues. I wasn't sure I believed the reviews people had written regarding placement on the effects chain, but yes! It's true! You can't put anything in front of it. Believe it or not, I thought I was heeding this advice when I put it first in my chain after my tuner - surely a tuner won't be a problem. Wrong. Behind my Boss tuner, the Double Muff has the trebly shreddy tone, just as was described by others. Move it in front of the tuner, and the problem goes away. So, don't be discouraged by this pedal, but just be respectful of it's requirements!

I am posting that under "ease-of-use" because, when used properly, it is not a sound-quality issue. EH should have instructions that say this, and I am not sure if they do, since I bought mine used.

Used this with Fender Twin Reverb. Signal chain is:

Stratocaster/Telecaster
Double Muff
Boss Tuner
Boss Compressor
Fulltone Fulldrive 2
Tube Screamer
MXR Phase 90
Boss Tremolo
Line 6 Delay Modeler
Line 6 Verbzilla

In the first slot, the pedal is fine. I did not notice any appreciable noise from it, other than what you get when you have any distortion pedal.

The tone is good for a vintage, smooth, medium overdrive-to-distortion. The reason I chose this pedal is because it is *not* gritty, and not metal-like, and it does not do any significant high-pass filtering, compared to some pedals.

It is probably similar to my old RAT pedal, with 2 functional differences. First, it has the added "double" feature, which lets you get a more feedback-y tone, while still not necessarily becoming shreddy. Second, it has the LED indicator, unlike the RAT, to let me know it's on. There's no tone control, but if you put it on double, and keep the Muff 1 set low, and turn up Muff 2, that's sort of like a tone control, because it gets more treble in the tone. My preferred settings are in the 8-10 o'clock positions for both knobs (whether you choose single, or double).

Other than the signal chain requirement, which is kind of bizarre, it seems like it may be reliable. I don't think I'd bring a backup, because I have 3 distortion-producing pedals on my board, and if this one failed, I could manage without it.

not sure

This pedal could be used for *everything* in a particular genre of music because it does not kill the low end of the signal - it has a nice tonal quality. I would not, in any way, liken it to the Big Muff, because they are night and day. The Big Muff, to me, is like a niche effect that works best on leads, and is a bit too much for most things - this pedal is more of a meat and potatoes distortion pedal with good tonal characteristics. I would suggest adding a second switch for doing the single/double, and I might even do that as a little project, since it shouldn't take a rocket scientist to do that modification.

Just got this 2nd hand off eBay. It seems to be reasonably new. Came with the wooden coffin but no manual. It's easy to use though - 2 dials and 1 switch. The switch selects between a single Muff circuit or a cascaded double Muff circuit. The dials control the distortion level, or level I'm not sure, of Muff 1 and Muff 2; so you can mix in how much you want of each Muff, or how much saturation/distortion each Muff has, when you have the double switch engaged. In single mode you get 1 Muff circuit and only 1 Muff dial functions. Couldn't be easier really. And in the usual E-H tradition this is quite a unique unit. Easy to get going. So high marks here.

Wow!!! What an awesome sound. I've owned a Sovtek Big Muff from the mid-90s before and that was an inconsistent sounding but fun pedal. Some days it was great, on really hot Australain days it sounded awful. (I lent it to a guy who is now reasonably famous and I never got it back). But, this Double Muff is much better overall, though it does have a Big Muff quality to it, it is very smooth, quite compressed sounding and easy to dial in a good tone. You do have to spend a bit of time in double mode trying to get the right balance between the 2 Muff circuits, but it's not overly difficult to dial in a usable sound.

I'm playing through a variety of very well made Korean copy guitars by Custom Guitar Workshop Australia - a WGR Hybrid (Strat copy with passive EMG Select pups) ST-2 (Strat copy with GFS humbucker in bridge + 2 GFS single coils middle & neck) TE-1 (Telecaster copy with GFS Hot Lead in bridge + Vintage Alnico in neck) Jazz Custom 607 semi-hollowbody (2 EMG Select passsive humbuckers). These are going straight into the Double Muff > Danelectro Fab Overdrive > Front end of a (Black and Silver) Transtube Peavey Studio Pro 112. Through my effects loop I've got a Danelectro Fab Chorus > Fab Flanger > Zoom G1 Multi-FX which I just use for tape delay sounds, nothing else: various presets of 200ms, 500ms, 600ms, 750ms, 1000ms etc. (This Zoom unit is going to be replaced by a more lo-fi product soon).

I've been using the Double Muff on top of my dirty channel. I use a reasonably low-gain, grunty rythm sound and this pedal gives you a really nice gain, and a slight volume boost, for sweet, singing leads. In single mode it's similar but not as intense as the double mode which gives you almost endless sustain. On my dirty channel this is not a Fuzz Face type sound. It's an ultra-creamy and smooth distortion with a slightly compressed quality. Similar to the Sovtek or NY Big Muff with the sustain knob turned up high.

Compression is not as noticable in single mode and the definition is probably a touch better as more top end is retained. The single mode seems to work better on the clean channel of my amp where the double mode doesn't sound so great. On the clean channel the double mode sounds more like a Fuzz Face/60s-type fuzz which is really nasty and low fi. Kind of like a buzzsaw. On single mode you get a light, but slightly raspy overdrive. Single mode would be good to send a cleanish valve amp, like an old Fender, into light overdrive.

It seems to me that the double mode with both dials, more or less, around the 50% mark on top of my dirty rythm sound is the most useable for me. It gives a great singing, musical lead tone, rich in harmonic content that is really smooth. It also helps attain some nice feedback. When I engage my Fab Overdrive, set to preamp boost (0% Gain, 75% Tone, 85% Level), which is next in the chain, on top of the Double Muff you get endless sustain which is great for legato work. The Double Muff also sounds great with my flanger engaged and it accentuates the effect quite nicely.

An absolutely great sounding pedal. It adds an extra layer of gain to my dirty sound and just smooths it all out. It's pure creaminess and I love this sound!!! It doesn't really give you the brass or tuba-type sound that Lindsay Buckingham got on some of Fleetwood Mac's Tusk tracks, it's more of a compressed, sustaining and smooth sound overall. Very Gilmour-esque. But it may depend a lot on what type of amp you use with it.

It's hard to know. My old Sovtek Big Muff always worked but sounded different every time I used it. This doesn't seem to be like that and it's built tough. It has a sturdy metal housing and a strong switch. I'm certain it'll go the distance. But, I won't rate it right now.

Unkown. I usually contact companies via email for advice if I have any issues with their products that I've purchsed. I'm sure they'd be fine to deal with but won't rate this either.

I play blues, 70s-style rock, some jazzier type stuff and a bit of effects-laiden experimental music. Most of the music I play I come up with. I've been playing since '89 and have tried out a raft of distortion devices in that time. DOD, Marshalls, Boss etc and a lot of them were useless in a live band situation. They just didn't cut through the mix. I liked my Sovtek Big Muff but it was too inconsistent. I really like my Danelectro Fab Overdrive, cause it's cheap and even with the Gain knob on "0" it gives me a great volume boost for leads with a classic 80's-sounding gain structure, but the Double Muff sounds great too and it's more of a 70's saturated lead tone - it's now going to live on my pedalboard. It's a good size too, much smaller than the Russian or NY Big Muffs or even the Little Bug Muff. I highly recommended this pedal; I got it for only $100 AU. Nice value for a top class musical-sounding overdrive/distortion unit.

Reasonably impossible to get a bad sound as far as I can see, and it's by no means difficult to get the exact sound you want. Afterall, there are only 2 knobs. Don't bother with the manual.

Basically, on single mode you have a volume knob. The pedal gets louder as you turn it up. That's about it. But that sound in itself is quite a nice vintage crunch, and in this mode the pedal can act as a volume/ gain boost I guess. In double mode, a whole new world opens up. Muff 1 still acts as a volume knob, but now you have a gain knob as well, which can be turned up to a very smooth, dark Big Muff-ish sound (notice the "ish". Not quite the same). When you play about with the 2 circuits, they mingle together in different ways, so you can get a very good range of fuzz tones, through some Hendrix all the way to that great dirty fuzz sound like on Mudhoney's Superfuzz Bigmuff. I nailed the sound of "Touch Me I'm Sick" after 5 minutes playing in the shop. Drive it harder and you're in J Mascis territory. Run it through another overdrive pedal (like my Vox Big Ben) and you can get an insanely thick, syrupy Joe Walsh "Hotel California" solo sound.
This pedal is one of the most versatile distortion/ fuzz/ overdrive boxes you'll ever stand on. Hopnestly.

Well, I only bought it today, so what can I say? Seems solid enough. Time will tell I suppose.

Not dealt with them.

Love it. I play a Gibson SG and a Fender Jaguar through this, followed by a Dunlop Crybaby, then a Vox Big Ben overdrive, in a Marshall AVT50. Basics of my playing goes through lots of 60s/ 70s classic and prog rock, Hendrix, Led Zep, Floyd etc, with bits and bobs of indie, post rock and grunge. This pedal can do pretty much all of it. I know I should probably get some chorus and delay and stuff on my board, but for kickass leads with a lot of tonal versatility, this setups brilliant. The Double Muff opens up dozens more possibilities. It makes you want to play more. It does it's job.

Distortion and volume for doulbe muff and vlume for single muff, easy!

I am writing this as an update to my first review (I'm the one who put no opion to everything), I have found that my assumption about my solid-state Crate's byass against pedals made it sound funky and have refallen in love with that classic tone, partially beacuse I just got a Peavey Delta Blues. I has a great tone, however there still are some set backs, it still has to be the first stomp box you run into or else it gets trebelly and noisy and the other problem I'm starting to have is that it cleans up to much with lowered guitar volume. It sounds great with a borderline "too much distortion" tone with the guitar all the way up, but when I turn the volume down to eight for rhythem playing, it's too clean for what I need, I've already got my Bad Monkey set up for the slightly distorted tone.

Seems reliable enough, but I've only owned it for a few months. Also, I put it in a pedal board case so it's really not moving or being exposed to anything so it should last a long time.

Never used them, although it is annoying that you have to spend five dollars to send it in for repairs.

It's a great distortion pedal, I'll just have to figure out how to get around the voulme issue. The only other thing that annoyed me about it was having to use as male converter to use it with my Godlyke power supply so installed a conventional adapter out (I should have gotten the one with plastic surrounding it, it took my hours to figure out how to insulate it from the chassis). If you're looking for that classis 70's fuzz box sound look at this and see if it works for you!

I am very happy with this pedal. It is rather simple to get a good sound out of it. 2 modes of 'Muff to play with (single and double). It is versitle and simple to use.

I play in an original band that charts the waters somewhere between the pop sensibilities of The Go-Betweens and the sparceness of a a now-defunct post-rock band from Melbourne called Sandro. I play mostly clean sounds with some light flanger/ phaser and delay thrown in for good measure.

At the moment, my set-up looks like this:

'79 USA Strat->Telenordia Kompressor->Electro Harmonix Double Muff->MXR Flanger->Boss DM-2 Delay->Electro Harmonix Small Stone Nano->Ernie Ball Volume Pedal (connected to Boss TU-12 Chromatic Tuner)->Flextone Line 6.

I sometimes also use a Maton 12 string acoustic guitar.

The Double Muff is great for crunchy chord work. I don't really solo - so I use it for a colouring agent for my tone. I use the single Muff and have it at about 10 o'clock for a gentle wash of dirt. Together with my Telenordia Kompressor [a truly awseome pedal] - the Double Muff has a high gloss sheen and sounds really punchy.

I could use a setting on my Flextone - but there is nothing like quite like jumping on a box to make you sound like a god. This pedal works for me.

It is very well built. I see no reason for it to die.

Haven't had to deal with them.

I've been playing for 16 years. Before the Double Muff, I had a Boss OD-1 [which I recently sold on eBay]. The OD-1 sucked all the tone out of my signal and in the end became quite a noisey little unit.

As I said earlier, I play mostly clean and play in Single Muff mode with the knob at 10 o'clock. What I like abou this pedal is that I ever wanted more grunt I could easily drive the knob further around and then if I wanted to go insane - kick in the Double Muff and crank it [this could have great potential for recording purposes].

My only criticism is that the 'jump' in effect when you step on it is fairly pronounced. Even at the low setting I use it at - the difference between true bypass and activated effect is large. There is a sizable jump in signal output - but hey - this is an overdrive/ distortion pedal - so what do you expect! If I had my way, I'd probably get a little mod done so I can control the volume output level. This is a small thing. When the band is playing around you and you are rocking your little toosh off...a bit rocking dirt fest is alright.

So overall, a versitle little stompbox. If you want a subtle pedal with a nice overdrive...or if you want a big fuzzed out effect - you cannot go past the Electro Harmonix Double Muff.

The easiest stomp box in the world to use, but you can't put it behind any stomp boxes or else its sound quality will be degraded.

Has a very good sound, very fat and intense, however, the good things stop here! You CAN NOT use this thing with other stomp boxes. Although the bypassed sound and the other pedal's sounds will remain the same, it absolutly destroys the Double Muff's tone. If you put it behind any pedals, it will get an annoying trebly sound and if you put it before all you pedals, it will get overtones with termelo in them (tested with a Digitech Bad Monkey Overdrive, Korg CHR-1 Chorus/Phaser, and Arion HU-8500 tuner). This isn't too bad when you play chords, but if you play leads, it can be very annoying, expecially iwith the neck pickup. However, these problems could be with my particular (Crate GLX65) or a particular vibe that I don't get so I can't be rate the tone. But this does suck, I got it so I would have to mess with my bad monkey in live shows to switch between low and highly fuzzed tones. I am using it as my slight distorter (in two muff mode) beacuse it seems less finicky with those tones. Bottom line, buy it if you want to use one awesome effect or mainly play chord based rhythms.

It seems reliably made and from the battery compartment, it looks parts are easily accessable for when I start wearing this thing down, but I've only oned it for a day so I can't vouch for Electro Harmonix's job.

Never tried

The only reason I wrote this review is to warn people about what happened. There are two things I need to add, first the sounds can gear related and it inconsistantly makes noise. I would check this out thouroughly if I were looking into buying it.

Two knobs, easy.

IMPORTANT: like other guys previously mentioned, put the double muff FIRST in your chain, even before the wah.
Else the DM will become very thin and trebly. I found that out myself. Try it and you'll be amazed. (true bypass effects can go before the muff, I found out, but certainly not Boss effects, which have a buffer bypass.)
I widh it had a tone knob, like the big muff.

When put up correctly, HOT tones and screaming leads.

The box works really easy. Just one knob, one selector switch and that's it.

The box doesn't work independently: the amount of distortion changes when you change the volume on your guitar. So when I just want to put my guitar a little harder, the distortion increases. That can be quite irritating, but sometimes heaven.

I use this stomp box with my Gibson Nighthawk and some different amps (mostly Vox, Fender and Samick). With tube-amps the sound is warm and brings character in your sound. With a transistor-amp, it sound more like noise.

The doesn't make any sound when turned of. But I usually have it switched on with just a little distortion because I am in love with the character of te stompbox.

I always gig with this box, now for half a year. It never let me down.

I always try to guess how a stompbox will survive and I give this one about 5 years.

Never needed customer support

I play most of all pop rock, now performing for my second year. It is a great match, it is now a part my sound. My other gear includes a Gibson Nighthawk, a Vox Valvetronics amp.

If it was stolen, I would buy another EHX effect for I need the tone. Problebly this one, because it works so easy and I don't like endless time trying to find my sound. This box is a part of my sound.

Compared to some boss pedals or line 6 distortion it had more character.

three knobs seems easy enough. try using it alone first and tweak your settings without looking too much at the dial numbers on your amp or the pedal. this pedal will sound different with every guitar, pedal, amp, and variation of the three that you use, so i recommend spending some time just listening to setting changes (rather than using pre-sets).

someone said they bought this pedal because they wanted the neil young "into the black" sound. that pretty much sums it up. you have to tweak your amp settings to get it to be bassy enough though. this pedal can be very trebly if placed at the end of an effect chain. place it second in the chain, right after the wah.

i don't recommend it for straight up guitar fuzz. i think it functions much better as a lead pedal. the big muff (with an eq run after it) is much better at plain fuzz (think weezer pinkerton, neil young tone on weld).

it is noisy, but that is why i bought it. i use it in front of all kinds of stuff: snarling dog wahs, heavy delay, chorus, tubescreamer, etc. this pedal is good at getting gnarly sounds, but not so good at getting refined fuzz or distortion. i guess that is why it is called a "double muff".

i run it through a single coil strat for added noise and feedback. my amps are typically 30 watt 1970's traynors and fender twins.

built much sturdier than the non-NY big muffs. i always have a back up because i break a lot of stuff.

this is where too many of my fellow reviewers tell the rest of us that they 1) play all styles of music (very well and for a very long time), 2) have more guitars and amps than leo fender, or 3) harp about how in the old days the things they played through were built out of pristine redwood from an extinct elfin forest and nowadays we have just lost the drive to make things the american way. tell that to flint, michigan my friend. oh wait. sorry. i too am being an asshole.

anyways, i recommend this thing as a noisy lead pedal (which is what I wanted) or as a novelty distortion pedal. if you want a more balanced and versatile fuzz than go with the big muff.

I think that this pedal is pretty easy to ue after screwing around ith it for a few minutes. In single muff, the Muff 1 knob controls the volume and the distortion. In double muff, the Muff 1 knob acts more as a volume, but still controls half of he distortion, and Muff 2 controls the layer of sludge you can get on top of normal distortion.

I can most certainly get that broken up distortion I've been looking for. The pedal is a little noisy if you have amp distortion on too, which I assume most people wouldn't do but I do. I usually run this through an Orange 30 watt combo amp; it sounds great.

You can certainly use this for a gig.

Haven't dealt with Electro-Harmonix.

A great pedal for dirty to filthy distortion.

I wouldnt say its easy to use, maybe not as straightforward as looking at it would suggest.
In single muff mode one knob controls the output of the muff, in double one controls the volume and the other controls the amount of second muff added.
The thing with this pedal is it is very dependant on what gear you are using it with.

I wanted a retro sounded for just one or two songs my band does and it achieves this pretty well. Its much better when used as a boost on your amps overdrive channel, seems a bit thin on the clean channel. There are a few variations in sound as you twiddle with the knobs and switch, but the big difference comes when you change pickups / guitars. This sounds completely different with a strat to a tele, for my ears it makes bridge pickups a little tinny sounding but adds some real beef to neck pickups.
It doesnt sound like any other overdrive or distortion pedal, I would say its a fuzz pedal with buckets of fuzz.
i dont think it adds extra noise but all my guitars have lace sensors, poor pickups make everything sound worse than it is.

No reliability problems. battery seems to last well. Wish manufacturers would decide on a power adapter standard. This is a male (crybaby wah) type not a female (boss) type.
Seems sturdy and tough to me, and has survived a pint of guiness kicked over it.

Not used.

I love the retro look, the name, the wooden box it comes in, and the fact its a bit different to your standard fare. It seems good value i think i only paid ??34 brand new cant quite remember but thats the area. dont know if id buy another would probably try something else, but only because i like a change.

This pedal provides the neccecities needed for a very unique kind of fuzzed distortion. The only minor, and I use the word to it's fullest potential, minor compaint I have come to know after two years use with this particular pedal: The actuvation slider switch for the second muff, But I usually end up usuing only the first muff in conjunction with my personal amplifier on the verge of shimmering clean near- breakup, this really does add cream to the crop, with only the single muff, the second really is not needed for most situations in my gigs.

The sound of this pedal is very excellent, (when using the single) untill the dial is turned past, ok say around one 'o clock, there is a certain "constipated bumble bee" sound as I would describe, which manifests itself after this point, but nevertheless, it is unique sounding; some people may like this (I do at times) and some don't.

Excellent true bypass, really reacts very well with volume petometers on your guitar, if turned down on double mode, you get the crisp-est clean you can hear, very unique, and then you could say, turn back up for a very raunchy ball of beautiful distortion pushed past the comprehension of man, sound.

I haven't had to deal with the Electro Harmonix staff, but the pedal is bult 'very decent'.

Good, very good for what it does, but it is still a high gain/ fuzz box, you can get a certain amazing clean sound with your guitar volume turned down, but otherwise, it is a pedal you like or dislike. have fun.

Two gain knobs (Muff 1 & Muff 2) and two switches (Effect On/Bypass & Single/Double Mode).

It's easy enough to dial in a wide variety of sounds. Muff 1 sets output level in both modes; Muff 2 is redundant in Single mode and affects the input gain of Muff 2 in double mode.

The manual states in Double mode, Muff 2 sets the output level of Muff 1 but I think that's an odd way of putting it. (Maybe I'm just being picky)

I give it an 8 for the basic reason that switching the 'Double/Single' switch with shoes on is nigh on impossible. I'd have preferred a regular footswitch to toggle modes with.

It's worth mentioning at this point that I play bass and have so far been dissapointed with every distortion pedal i've used.

Ok so I took the pedal out of its wooden box, plugged in and instantly managed to dial up some lovely fuzzy QOTSA tones from subtle 'Burn The Witch' stuff to heavier 'Skin on Skin' growlyness.

The distortion sound doesn't sap my low end like most guitar pedals and doesn't have a dissapointing blend control like most bass pedals. In a nutshell it inhances my tone instead of stamping a brand name on it.

I'm currently using a Tanglewood warrior III that has electrical problems. Basically i have to roll the treble off otherwise I get a really noisy signal. However I have used this pedal with a P-Bass and got amazing results.

My advice is get a smart gate or something similar because, especially in long signal chains, this thing is the noisiest pedal I've ever used. At high gain settings it seems to compress the signal somewhat and when not playing hisses at the same level as the bass' output!

I give the Double Muff a 9 on sound purely because the tone section on the original Muffs has been completely removed. It reacts very well when used with the passive tone control on my bass but I'd still enjoy a promitive eq section on the pedal itself.

I wouldn't stamp on this like I would a Boss or MXR/Dunlop. The thin metal housing seems flimsy and after only two weeks of ownership i can see the metal bowing around the foorswitch.

The plastic casing on the underside was warped on arrival and the whole build seems a bit light.

Also the screen printing scratches too easily; not that this is a major hassle as the controls are memorable if it were to wear off completely.

I would, however gig without a backup. Unless I jumped with both feet on this, I can't see it breaking mid-gig. I think i'd notice when to get a new pedal to replace this one.

I am, however worried about its overall longevity and that's why I'm only giving it a 7.

Never dealt with them.

Right now I'm in a synth-led indie rock band. Our musical scope, however is quite wide. I hardly ever like playing bass clean so this pedal's perfect for adding a little crunch when needed and a nice mid rangey growl for heavier sections.

I've been playing guitar for about 12 years and bass 3 of those and this is by far the nicest distortion tone I've come across.

My current rig is as follows:

Tanglewood Warrior II Bass > Boss TU-2 Tuner > Boss SYB-5 Synth Bass > Dunlop High Gain Volume > EHX Double Muff > MXR Phase 90 > Boss CH-1 Chorus > MXR Bass D.I. + > Laney Bass Amp.

Even though, as I said earlier, this is the nicest distortion I've come accross, if it were lost/broken/stolen I'd invest in a couple of Russian Big Muffs and a line selector pedal for the extra versatility in tone offered.

As mentioned in the Ease of Use section, I'd prefer a footswitch to change between Double and Single modes, but I can see why EHX have opted, in such a compact unit, for a switch that can't as accidentally be pressed.

I've never been subject to a distortion so dynamic and attentive to my playing as this. It's not so easy to hide behind as some other units and really accentuates my playing style. As a result I've become alot cleaner in the way I play.

The Double Muff can either sit back in the mix or become a dominating part of it. In this respect it has become a major tool to go to when writing bass parts.

Overall I'd love to see an eq section on this pedal, something that so far is only available by buying two Big Muffs, but for 32 quid (the cheapest pedal, not made by Beringher, I've ever seen) it's well worth having a look at.

Very easy- One switch, two knobs- However to acheive a good sound other effect pedals/amp-built overdrive may be needed.

First things first: This is an AMAZING pedal! I've been using it for a year now so I think I am allowed to say what I think about it. This pedal can be used from Jimi Hendrix Fuzz to Metallica like distortion. I play alot of Queens Of The Stone Age and Foo Fighters myself and I find if I turn down the tone on my guitar, these sounds can easily be acheived.
!!HOWEVER!!
I found it VERY hard to get much distortion on its own, with absolutely no help from the amp. If you have a good sounding, non-bland amp (modelling amps would work too) with built in distortion/overdrive then this is fine, otherwise you need to buy another pedal to boost this one.
If you play bass this pedal gives the perfect amount of overdriven deep+throaty bass without any help. Very good for a Nick Oliveri bass sound, especially for songs like "Give the mule what it wants", "You would know" or "

Not only has it been great this whole year but I've only ever changed it's battery three times!

Electro Harmonix are very friendly. I dont know how much support they'd give though, I've never had to use the waranty.

This pedal is BRILLIANT, its fuzz, its gentle overdrive, its metalic distortion. Unfortunately the pedal may need a little push. The best thing about this is that No-one uses it. It's the most accesable and cheap electro harmonix pedal avalable yet everyone prefers to use the over-rated Big Muff. My friend bought one after seeing how good my sound could get and naturally thought this would be better. Despite its need for a boost, my Muff sounded much stronger than the classic. Use this for an Unique but varied sound

Pretty easy to obtain decent tones from this box,( particularly fuzz
if that's your cup of tea.) Cleans up nicely with the guitar's volume
knob like any good fuzz box.

Very noisy on its own....I have a Ross distortion box in front of it
which acts as sort of a noise suppressor/limiter. I also use an old
Boss CS-1 compressor in front of it. It is pretty tweakable tonewise
this way. Otherwise, particularly on Muff 2 very noisy. I can get some
decent fuzz tones from it(which is the sole reason I bought it.)

Seems fairly well made. It's my first EHX box so I'll enter "No Opinion".

Absolutely no idea, but for a $65 pedal I really don't think I'd
bother.

Excellent value for the price. A decent fuzz pedal with true bypass.
It really is noisy, though. Some sort of noise suppression device
is needed.

It's simple to use, really, but kind of hard to understand. In single muff, mode you just get more boost as you turn the knob up. Double muff is less straight foreward. The knobs both do the same thing but in series. I find I kind of end up using Muff 1 as a master volume and Muff 2 to control the distortion. Really, I just move them around until they sound good, which isn't hard but the dynamics of the pedal do change a lot and it's not so straight foreward as pedals w/ a gain, tone and volume knobs. You basically have two volume knobs here that interact.

Despite the guess in check methodolgy you have to use to get it set *just so*, I think it sounds pretty great no matter what in double muff mode. It's a little fuzzy (less so than a Big Muff), a little overdrivey and a little bit like a distortion pedal. I've found w/ my amps (Bassman 100 into six twelve inch speakers among others), it has plenty of low-end, tons of harmonic richness and responds well to palm muting. It's not as tight as, say, a Rat or a Metal Zone but has a warmer.

I don't get much use out of the single muff mode. Actually, I never use it. It would make a cool lead boost, I suppose, and sounds pretty decent for bass.

A lot people seem to have trouble w/ this sounding thin which is entirely not the case w/ mine so either theirs lemons or you just have to happen to have an amp that works well w/ it.

I use it w/o a backup all the time but probably shouldn't. EHX makes some great sounding stuff but it seems like the cheap out on the construction which makes them unreliable to some extent. Just because it's made out of metal doesn't make it sturdy. I shudder to think of all the metal-cased BOSS pedals in the great pedal grave yard.

Never had to deal w/ them.

I use this for some metal but I don't go for the typical scooped high-gain sound that's common. I like a more vintage (but still saturated) distortion sound--more "hard rock" than metal. I love it's thick rhythm sound for powerchords and it's overdrive w/ a fuzzy edge gives a unique character vs. pretty much any pedal you can get on the market. I wish it was called something other than the Double Muff; it seems like that makes people come into it expecting the wrong things.

I got this sucker for forty bucks and I would have been happy to pay twice that. I suppose I would like some tone controls but that might just mess up the mojo it has w/o them. Simple is often best. If you happen to have a setup this will work well in, it's a real treat to play w/ though it's not versitile enough to work in every rig.

Cannot be easier. Two knobs, one selection switch, power on/off.

I am using a Gibson SG Standard > Fender Champion 30W solid state amp.
The pedal as two modes - the double and the single.
Singel - Deactivates the "MUFF2" knob, so the gain/volume will be now controlled using the MUFF1 knob. Yes, gain AND volume. Lack of volume control becomes the "single" option to be unversatille, if a balance between the clean and the overdrive is required. However, the sound is accaptable for it's price. A very fair booster, a bit crunchy but I guess that's fine.

Double - Activetes the MUFF2 knob. Now, the MUFF1 will be used as "pre-gain" and the MUFF2 as "post-gain". If you like to blance between the both channels- You would be needed to balance between MUFF1 and MUFF2- Higher volume at MUFF2 will increase the volume and lower volume at MUFF1 will decrease it. The sound using the double opetion remainds me the Boss DS-1.

Seems pretty solid. This one is 3 years old and looks like a new one.

Lack of EQ and volume makes this pedal very unversatille. Don't let the name confuse you!
I wouldn't define it as a fuzz. It is booster and distortion, but none of these two options are versatille.

I wouldn't buy it again. Overall, it has pretty fair sound, but even at it's price you can find better stuff. However, this is a second-distortion. Don't use it as your major one.

Muff 1 and Muff 2 level knobs , single or double muff mode.
Nice box , missus.

Performs slightly better with humbuckers than single coils.
Also performs slightly better when left in the cupboard rather than connected to a guitar and amp.
Sounds like a broken transistor radio playing through a torn speaker cone , total garbage unless you need a novelty guitar sound.
Bought this on a whim off the net , big mistake , the only use I have for it is as a bass effect , passable for that.

Typical EH build quality , stupid battery access.

Tried to ask them some questions about it , but the boss was busy on his yacht snorting charlie off the top of dwarfs heads , whilst paying peanuts for his overpriced effects to be made in sweatshops in Asia , and selling the to dickh8ads like myself.

Doesnt matter what style of music you play , this pedal is unsuitable.
Dont be misled by the 'Muff' bit , its just that they couldn't call it 'Double Shite'.

It is very easy to use

The sound depends of the need of the player, single muff is very soft booster sound, though the output volume is very high, at the maximum it sounds a little noisy, good for blues rock of the 60 & 70.
both muffs sound very cool especialy at maximum, same output level who's very high.
if both are turned to maximum sometimes a little noise appears, but after all the harmony is excellent also for chords, with a very cool fuzzy sound, I tried to play voodoo chile, purple haze of jimi hendrix and also some rage against the machine and sounded pretty cool especialy if connected with the cry baby (jd original).
it is a little pedal but the sound that comes out is much better than many digital distirtion or ampli booster.

I like to play many styles from classical to jazz, what is important is the harmonic passage from a clean sound to the sound thru' 2muff.
i use a cutaway classical with bband & micro, a fender stratocaster 68, marshal vs, different pedals as chorus flanger cry baby.....
i actualy wanted a fuzzface but was attracted by the low price and and the good quality of this product.

Not much to screw up here. 2 "channels" controled by a switch, the single controlled by one knob and the double is controled by both knobs. It seems to me, on the double channel the Muff 1 knob adds volume more than anything, but the Muff 2 knob controls the fuzz. Ease is a very important factor to me. There is no manual, just a short paragraph on it and that is all you need.

I have a bad setup I have a Daisy Rock, Rock Candy Special (which I love) but I play out of a Randall RH100 G2 head (sux) and some crappy speakers that I am replacing next week. However, it is a stellar upgrade from the amp effects, and after playing through some tube amps at the store, I know it will be a pedal that I will continue to use after I upgrade my gear. I have a Boss Mega Overdrive which I will sometimes use in conjunction with the Muff. It really carries.

I'm in an original band-I love Queens of the Stone Age but my band is a little more punk/metal than them so this is great hybrid of Josh Homme's fuzz and a distorted sound. With the single muff I can dirty up my clean channel, and have that fuzzy feel. With the Double I can be fuzzy dirty or add in my Boss pedal and I am Death Star

My ONLY two cons. It is very loud, I will have to adjust my other pedal and my amp to compensate for this, it is something I will have to deal with at every gig. Second I was hoping for a little less overdrive. For the price that I paid for it why the f&*K not! The other concern is that this is more of a distorted/overdrive fuzz so if you are going for 100% fuzz you might want to try a different pedal. To me this is about as close to perfect you can get for under $60

I will still use my Boss Mega Overdrive but so far, this seems like a well built piece of gear. Haven't gigged with it yet, but it has worked for the couple of hours I have played it.

Haven't dealt with them

I've been playing about 3 years, 2 of them in a band where we play hard rock/metal/punk music with a melodic touch. This is a great pedal for me I am in love with it and if I had to replace it at this point, I would. I am just starting to get heavy into gear and this pedal has increased my options and seems to be something that I will always use even as I build my arsenal.

This is a great sibling for my Boss Mega Overdrive and it eliminates me using the crappy built-in effects my Randal RH100 G2 has. I could see where more seasoned players or people that want a specific sound would shy away from this pedal as it doesn't seem like traditional fuzz. It is just fuzzy enough for me and if you are a non-believer in processors like me, you can hear a lot of sonic capabilities with this pedal.

Esay to use. 2-knobs, muff-1, muff-2. 1-switch engages one or both. Pedal switch. Easy to get a good tone.

Gibson solid bodys into Marshall JTM-45 reissue and Marshall 4x12. Alittle noisey, not bad. Simple, Set the knobs for your own tone. Works well with others(pedals that is). Effects chain= WAH, OD, DBL MUFF, DISTORTION, PHASER, DELAY. I can get the sounds I crave from the old recordings up to and including the new rock stuff on CD. Its a keeper for me. I wont bore you with who are my favorite guitar gods,,,theres too many. I love this little box. Yeah-----Elecrto Harmonix--BRAVO !!!! It can act alot like a treble booster, Fuzz, Distortion, Overdrive----its way cool. It depends on how you set the two knobs in conjuntion with each other. Some folks said it was hard to set a even output level, not me, I just use it in the double muff mode and use muff one to set a output level. Did I say I love this pedal. I give it a 10 for range sounds and price.

Ive had a small stone for 4 years now--no problems. This is built just as good.

NA

We play classic rock, POP, oldies, New stuff. This fits in my chain well. Im too old. I would buy again. I Love the range of sounds. I dont hate anything about this pedal (it looks cool, like all the EH stuff has for years). I sold a custom handmade range master and got this used for 1/4 the cost. More versatile IMO. I dont think it needs anything. It works well in our band situation. It helps me cop some of vibe from old recordings as well as newer stuff. Its a keeper on my board for the time being.

VERY EASY to use. BUT - it acts more like a light overdrive booster (muff 1) or a vintage fuzz pedal (muff 2). so you may have to use it like one of those - or both.
at first, i was worried about the "only 2 knobs"... one for muff 1 and second for muff 2. i worried about volume differences. but no problem here: muff 1 knob acts more like an overall volume, while muff 2 knob sets the fuzz/overdrive level for the double function.
that said - this pedal is very sensitive to your playing, use of guitar volume and your overall sound - i.e. amp!
i think, to help you choose or not choose it you still have to test it, bur don't expect either a bigmuff or a tube screamer. it's none of those, but imho much better than both of them!

my setup changes a lot. i'm an effect freak. i nowadays use lots of line6 things. so my chain is somethin like that: EH double muff > nobels pre-1 booster/or line 6 constrictor > ibanez tubescreamer ts10 > digitech whammywah > line 6 mm4 > line 6 verbzilla > line 6 echo park > line 6 dl4 (the letter change sometimes...) > hughes + kettner tube 50. i mainly play ibanez blazer guitars.

2 muffs: at first i got this one after the pre-1 and the tubescreamer, and everytime the guitar volume knob got over 5 there was a ugly wail. after some testing i put the doublemuff first in chain - quiet!
it is strange, but it seems to have to be in first place. no problems now.
the double muff was maybe the best thing i bought last year. i use it so much now, almost in every song. it's very versatile if you know how to use it. it would be great if you could switch between muff1 and muff2 via footswitch, but no problem here with kneeling down to switch.
against all my fears, theres no volume change between the two muffs, so there's really no problem swtiching between both in one song.

the sounds: just great. muff 1 acts as a booster, light overdrive. it does make your tone a little fatter AND darker/warmer. with an light overdriven amp, you easy get santana-style overdrive sounds. very good for soloing and bluesy or even jazzy tones.
muff 2 was the reason i banned my fuzzface from my board and now have space for some more pedals :-) it's IMO very near to a fuzzface, but nothing as muddy as mine (germanium). it acts very good with guitar volume. volume down to 5/6 you get a very crunchy medium overdrive (sound depends very much on your amp!). volume at max it's pure fuzz heaven. before a clean amp this is just amazingly heavy (i found out, that the muff 2 knob sounds best at maximum level - play with your guitar volume to adjust drive). if your amp is overdriven, you get a less distorted sound. it's rounder and warmer. with my H+K in heavy overdrive and the muff 1 it's wonderful lead tone. same with muff 2 and guitar volume at around 5. santana and D.Gilmour lead sounds here. very nice.

it's EH. it looks good, maybe is a bit huge for the insides, but nevermind. it's true bypass i think, the switch is metal and damn quiet. the switch is a little close to the muff 1 knob, but i am a careful guy!
i use this most of the time now. i never thought i would write something like that, but - how could i play without a doublemuff??? :-)

if you - like i was - seek for a good pedal for lead sounds - forget chorusses or stuff like that. this one makes your guitar sound very natural and yet stands out of the mix!

as it is not very expensive and you technically get two pedals in one - i may buy a backup for this one as it's so essential to my sound nowadays. (i never buy backups!).

have no clue. but i like their pedals (although this is my first EH pedal). they look good, are very innovative. capture the "good old sounds" and yet are timeless!
and - EH is way cool! i mean. they know how a pedal should look and sound!

i play in different bands. one coverband, so we have to play a lot of different styles and sounds. mostly i play shoegazing indiepop, 60ies/70ies psychedelic rock, 80ies synthiepop and indierock/new psychedelia. i am a pedal-freak. especially i love delays and phasers. and now the double muff. great gear.

Pretty easy to use, cause of only two knobs(though sometimes I wish you could control the tone but...)

I have an all american Fender 25th. Anniversary Strat and a Gretsch Corvette from 1961, and run 'em through the Muff=>Boss Bd-1=>Boss Gt-6 into a Sunn Model T reissue. I use a 4x12" Marshall 1960 Lead kabinet. Well that is my current setting, but I always experiment with the order of the effects, but now it sounds great. The Double Muff provides me with a rich fuzz that I boost with the Boss Bd-1. Then I just use the Boss Gt-6 to get the usual effects like delay, flanger etc.
Since both of my guitars are pretty old they're pickups seem to make a lot of noise when the Muff is fully on. But if I reduce the tone on the guitar, most of the noise goes away.
With this baby on and a phaser I can get almost the same fuzz sound Matthew Bellamy(Muse) uses in Plug In Baby.

Thats a tricky one... I haven't had it for a suitible period to actually grade that one.

So far, so good....hope it lasts!

I mainly play rock, anything from early rock'n'roll to the heavy sheit. Sounds great in my ears to what I'm playing...
I would buy it again if it should be stolen from me. It won the guitarist pick award and they are almost always right about things.
As said before, I wish it had the control functions the big muff has, at least for one of the two muffs.

Very easy to get a good sound out of it. its pretty straightforward how to use, nice knobs. the manual is as blatant as it gets so if you dont know how to use it after that im sorry you need more schooling.

Epiphone G-400 ---> Poly Chorus ---> Double Muff -----> Fender Hotrod Deluxe. i also have a big muff which i dont use anymore cause of this pedal. no hum, no squeeling, no unpronounced note. this pedal is the cure for mostly everything, it has sustain, volume, warmth. its very versatile, i can play stuff that ranges from deathmetal, grunge, punk, shoegaze, hardcore, and of course classic rock. anything you name it i can do it with this pedal. if you want feedback you press your guitar on a amp speaker or let it sustain and feedback. very grunge pedal i give it a ten. my poly chorus is awesome with it very pronounced compared to boss effects, this pedal sound similar to alot of others. but the poly chorus has alot of settings and this pedal accentuates all of them. it really is like having two boosts of the finest overdrive fuzz.

yes its very dependable it looks alot more secure then last pedals. (note if your not going to use adapters tinkering with the battery kinda sucks for this pedal because it tends to cause alot of problems with me so i use the mutli adapter i got from radioshack and it sounds awesome.)
defintely a goody if i take it anywhere its going in its bubble wrap box.

i have no experiance but they gave me a warranty card. i would rather fix it myself.

i play everything but mostly am inerested in noise bands and syd barret. i also love the pixies and this pedal sounds alot like the pixies to me. Ive been playing around 7 years. i would definately try and buy another this pedal is my personal fuzz from now on. my favorite feature is the double mode obviously, i wouldnt have liked it as much as a single alone its very two dimensional until you hit that double effect. iv compared this to ehx big muff(both russian and usa), boss ds-1, boss-md2, rat, turbo rat, boss xtortion, boss md-2, digitech rp100(distortions are crappy sounding to no ends). i chose this pedal because it has all the sounds i want and more it seems and its very affordable.

Simple and easy...Two drive/volume knobs one for each one of the two Muffs and the switch for the single/double mode.

Very easy to get nice sounds...if you know how to control the sound of your guitar...its output its the frequencies it gets at the the input overdriven!

There is a manual from EHX but you wouldn't need this...

Fender STD Telecaster/Ibanez RG-70 guitars -> Double Muff -> Boss DS1 -> Mini Q-tron -> Korg AX1 -> Boss DD-3 -> Danelectro Slap Echo ->Marshall JCM 900 head/Marshall MG412A 4x12",120 Watt cab

No real noise at all...only on very loud settings and when recording i found a little noise but not annoying at all. It's an analog pedal after all!
You can reach sounds from smooth overdrive to really nasty distortion. I play indie/alternative/post rock and I have found a setting that gives me the perfect sound for every occasion.
The muff(drive) knobs are very sensitive...even small changes can be clearly heard!

Come on now...EHX pedals are tanks!
Of course I gig it without back-up. Although I would like to have the money and buy 1 or 2 Muffs more to modify them by myself...

I have the pedal almost for a year and I've never had to deal with EHX for service or troubleshooting issues. Neither had my bassist that also owns some of their stuff.

Great stuff...I use it for its overdrive sounds mostly and I usually don't push it to its distortion limits. I use the Boss DS-1 for heavier sounds...but the truth is that I very much like the sound I get when I have the Double Muff in single mode with the knob at 11 o'clock and the DS-1 at full gain!!!

This little shit rocks hard!!! It is the best piece of stompbox equipment I've ever had in my Distortion section of the pedalboard!!!

It's lack of controls tended to make this pedal harder to use for me. The single muff mode is pretty straight forward and simple to use. The double muff is where it get tricky. It's difficult to get a good combo of resonable volume (so it doesn't drown everyone else out when you click it on) with a high ammount of fuzz. When I get this pedal really screaming it's WAY louder than my clean signal, which was a bit of a problem. Also, there's no tone knob. However, I had no problems finding a good array of tones using different pick ups/tone settings on my guitar. But here again I run into the problem the difference between my clean tone and the tone with this pedal. A set up on my guitar that sounds good clean might not sound so hot when this pedal is on. Also, the manual is nothing but a borchure.

I play a mexi strat through a 72 bassman ten. I just use a distortion pedal (either this one or a danelectro daddy O) and a tuner, pretty basic. I do love the sound of this pedal. It can be hard to get the exact sound you want out of it but when you find it, it's beautiful. It sounds a lot like my old russian Big Muff on muff 1 and about to 9 o'clock on muff 2 but after that it just sounds like a muff on steriods. Really loud, noisy lots of feedback. Perfect for me since I play bluesy garage rock (think MC5, stooges). However aside from my band I play blues and Jazz with friends and get good tones out of it for both of those (the muff one setting can be very smooth and quiet. Plus, the true bypass is an very good feature.

I've never had any problems with any EH pebals. They're tanks.

Never dealt with them. However, I did read in the manual that you have to pay shipping to and from if you send it in under warranty which I think is bullshit but they will fix it for free.

I like this pedal a lot, mainly because it fits well with my style of music. I wanted a pedal that was a little over the top, very loud with a lot of feedback and that's what I got. In addition to that I got a pedal and has a lot of subtle fuzz tones that sound excelent and very smooth which I didn't expect but were definatly a pleasant suprise. I really which they would've put a tone and volume control on it. But, If I lost it I would buy it again.

It's easy to get started, but it's hard to get exactly the sound I'm looking for. The manual doesn't tell sh*t, but that's no problem, had fun for a few hours trying to figure it all out.

I'm using a Fender Champion 30DSP with it. Works okay. It's nice to combine the single muff with the amp drive. The double muff gets outta control over 12 o'clock. Nice for experimental things. I have it for half a year, and I still think I can get a lot more out of it. The only thing I miss are a few more controls.

It won't need a backup. I accidently dropped a heavy whiteboard on it, gave some scratches, but no real damage. Everything still works.

I play a lot of styles. For my band I play surf and british old school punk. It's not the thing I was looking for, though it's a very good thing. I think it would be better if it had a little more controlknobs. I would probably buy something that suits my style better if it was stolen.
Ow ppl....stop giving 10's and 9's for everything, you like it okay, but 10 should only be for the very best you can get.

Some people comlain about how little is covered in electro-harmonix manuals. Honestly, I appreciate how they assume that you know a little something about what sound you are after and leave it up to you instead of giving you settings for this or that sound. The basic controls are described, and thats all you need. There are two knobs, and a switch for single or double mode. It's not difficult.

I play experimental indie/grunge rock and this pedal is awesome for it, especially with a lot of influence on my tone being from classic rock. The setup I am currently running with this active is: 1978 Music Man Stingray II (yes, it is a guitar, not bass)->double muff->big muff pi->Vox wah->EH Deluxe Memory Man->Laney AOR Pro Tube Lead 50w head->dean markley 412 cabinet. My entire rig is noisy because of the old school active electronics in the guitar but this pedal doesnt really add a whole lot of noise to the sound unless you have your volume all the way up (more on this later). The Deluxe Memory Man, strangely enough, gets rid of 90% of my line noise when its engaged. It can be a little tough at first to find your settings if you are really after a low gain sound, but it is very achievable, just not in the first place you might think to look for it. Instead of trying to find a low gain setting in the piece itself (you won't find one you like, it will be very harsh and unappealing) set a sound that you like as a nice overdrive and then turn the volume knob on your guitar down, this will give you a nice light grit or breakup on your cleaner sound. This being said, i have mine set for, when the volume is on 9 or so (if i go higher, the line noise comes back pretty hard) a nice classic rock overdrive (double mode, muff one on 2 o clock, muff two on 11 o clock) and then play with my volume down around 4-6 for most of my cleaner sounds. I get a nice slightly driven, barely gritty glassy clean to a smoothly broken clean overdrive sound that simply sings. Very effective with a Wah pedal with a slight chorus from the memory man. Its just a very musical overdrive. It has clean crisp highs without any overbearing tones anywhere in the sound, there's just the 'right amount' of mids, lows, etc. It just feels balanced.

Its built solid like all the other EH products I've owned (big muff pi, deluxe memory man). I havent had any problems with them yet. I feel comfortable not having a backup. Just make sure you have batteries with you (or find the 9v ac/100mA power adapter).

Ive never had to deal with EH. Their pedals do what they say they will.

Like I said before, I play experimental Indie/Grunge. Most is written in the lines of Pink Floyd, Bush, Stone Temple Pilots, Sneaker Pimps, Autumn Thieves, Autolux, and a bunch of Folk artists. I have played for 4 years now and own a '78 Music Man Stingray II, Epiphone Les Paul Standard, this, EH Big Muff Pi, EH Memory Man Deluxe, Vox Wah, '86 Laney AOR Pro Tube lead 50 watt head, dean markley 412 cab. This is an absolutely essential piece of my sound as it allows me to have exact control of a huge range of gain and distortion simply by way of my volume knob. On top of amazing functionality, they are so affordable that I couldn't NOT buy another if this was lost somehow. I have been using this for about 3 weeks now and I have been very happy with it.

Very easy to use. Muff 1 is a mild distortion and both muff 1 and 2
yield some great nice fuzz tones. Cleans up well with the guitar's
volume control.

Very good- my first Electro Harmonix pedal after many years of
playing the guitar. A lot of usable distortion and fuzz in this little
box. And true bypass for a $65 pedal! It is noisy with my rig, however, especially on the Muff 2 setting.

Haven't owned it for very long, but it appears to have a pretty good
build quality.The switch is a bit stiff when engaging and disengaging.
I use mostly vintage Boss and Ibanez effects and EH seems to be a well-made product.

Absolutely no idea on this subject.

A steal for $65. Great fuzz and a variety of distortions with a bit
of tweaking. You must run this effect first in the chain (if using
buffered bypass such as Boss)or it will affect the tone in a big way.
It does not have the endless sustain of its sister pedal, the Big Muff, but it is a nice pedal to own for classic rock. I'm seriously
considering trading some of my other pedals and buying more EH products.This baby is really a treat.

It has one switch and 2 knobs, if you can't work out how to use it you should put the guitar down and go sit in the corner.

I use the following set up:
Epiphone Supernova>Loooper>Vox Brian May Special (Treble Booster)>Boss GT-3>EH Double Muff>Boss MT-2>EH Small Stone>Fender Twin Reverb 65 Reissue
At first I was a little disappointed with the sound but when I started tweaking the knobs left and right and adjusting the volume on my guitar slightly it made a huge difference. Changes are very subtle but hugley effective, drop your guitar volume to 7 or 8 to give a nice light overdrive with the knobs turned halfway. Swithc on the single muff to get just a touch of drive, flick the switch up to give it some more kick. It won't give you a fuzz sound like the Big Muff but wack up the gain and you'll get some very good creamy sounds that compliment the Big Muff perfectly (my lead guitarist uses a Big Muff). Works great with other pedals too, phasers delays and choruses will have you experimenting with it for hours.

Sturdy build, excellent quality.

N/A

This is my favourite pedal now and I have it kept at the same setting. I know that when I gety bored though I can fiddle about and change my sound without losing what I had before, if that makes any sense. I have to make use of the volume on my guitar but I don't mind doing that, it jus tmeans I have a wider range of sounds. I play a lot of rock alternative type stuff and it is perfect. Not for metal heads but a great pedal to have if you like a variety of distortions with having the gain dripping out of your amp. For the price, everyone with a guitar should get one.

Two controls and a switch, very simple. The manual is a sheet of paper with a little text explaining the controls and how great the pedal is.

The Double Muff is not two Big Muff circuits as some people believe it to be but rather two Muff Fuzz circuits in series that can be cascaded into each other. The original Muff Fuzz units were simple boxes that plugged directly into the guitar jack which you would switch on with a slider switch.

I'm running a Gibson Nighthawk through a handful of pedals into two Matamps - a 1224 and a C7. There is a trick to getting the best out of this pedal which MUST be done to get the right sound. As stated in other reviews it is VERY important that this pedal is the first in your fx chain, no buffers before it. If you do run it after buffered fx the unit is VERY noisy (hissy) and the sound is thin and very trebly. As soon as you run it first in line the hiss disappears and the sound fattens up, the fuzz effect is more prominent and gets much closer to Big Muff territory.

When setup correctly as above the sound is simply outstanding! Smashing Pumkins springs to mind. The big difference between this and the USA Big Muff is that the Big Muff gets muddy in the lower registers - it doesn't like my amps at all really. The Double Muff IS NOT muddy at all!! Now I've got the Muff sound and no mud and can solo and chord all over the fretboard and it sounds awesome throughout!

The two settings available - Muff 1 and Muff 2 - offer a fairly large gain range. With the slider switch you go between the first circuit or both combined. Naturally the gain/distortion is more intense when cascading the circuits together but in either mode you get a nice bite.

Electro-Harmonix boxes have always been the same: folded sheet metal screwed together. The only problems I've ever had with EH stuff was a dodgy switch. As long as you're careful with your pedals they will gave you no problems with reliability. New EH pedals are wired for true bypass. As usual you get a silk screened paint job which do scratch very easily - that is to be expected for EH pedals and I wouldn't change it!! All part if the charm.

I've never had any reason to contact EH re any technical problems - I have e-mailed them before ona general enquiry and got a reply the next day.

I play rock, blues, alternative indie and this pedal is simply outstanding! I've been playing 10 years and have owned a Jimi Hendrix Dunlop Fuzz Face, a EH NYC Big Muff and now this. There is a whole world of fuzz pedals out there but I want the EH sound and this is it!! You will be hard pressed to find a pedal with value for money like this, only ?38 brand new and made in the USA!!

It is a pain that you have to run this first in line and the guys at Electro-Harmonix should really put something in the manual explaining that it is necessary to do this to get the best out of the pedal. I can imagine people rejecting the Double Muff if they don't know about this which is a shame because when setup right, this thing destroys all!

Ease of use is actually a lot harder than it seems. I mean, its easy and its not. It is cos its just two friggin knobs and a switch. Its not easy because since it is so limited in how you shape the sound, you have to fiddle around with your amp EQ a lot and the knobs and it varies BIG TIME from amp to amp. Like I said, its easy and not.

My guitars consist of a Gibson Les Paul, Epiphone Sheraton, Nelsonic Tele-copy, and some Dean Explorer-copy. I also use a Maxon OD808 and a Fender Blues Junior and I used to run this through my Fender Hot Rod Deluxe (but i recently sold it).

On single mode, the pedal isnt noise. On double, it is, but not any noisier than any other distortion pedal. Through my fender blues jr, the single mode is the mode to go with. Since the blues jr's clean is never 100% clean, it adds character and it sounds SO good. its bright and crunchy with a hint of subtle fuzziness. the double mode seems to get compressed too much and is a bit muddy. i can tweak out decent tones with the double mode through this amp, but the single mode sounds so good that i rarely bother.

through the hot rod deluxe, the single mode was very weak. but the double mode was BIG and nasty. I loved it. I like the sound i get with the single mode through my blues jr more, but the tone i got when using my hr dlx was absolutely killer. more similar to a smashing pumpkins tone (when they used the big muff).

like i said, the tone REALLY varies from amp to amp. I used this through my friends Fender Twin and it sounded like Neil Young's tone in Hey Hey My My. Obviously, I didnt have as much time to tweak with the amp and pedal as i did with my own gear, but the fact remains. The tone was cool (if you like all out raunchy fuzz sometimes) but definitely different from amp to amp.

I also used this through a PA. Lemme tell ya, not a good idea. Thin and buzzy. I've tried this through several amps, but the first three were the three i used the most with it. The rating for this comes from me using with with my Blues Jr.

I had a capacitor break on me. Not because of anything I did, but just because it was faulty. I'm not worried about it breaking though. Shit happens.

Like I said, a cap broke because it was faulty. EHX paid for the repair and part, but they made me ship it out there and pay for the shipping. It was only $7.50, but I think if I buy a pedal and about 2-3 later it breaks because of a faulty part, I shouldn't have to pay a dime. Especially if i registered the warranty already.

Could've been worse though. At least they were quick about it.

This is actually my second review for this. Its a follow-up from probably about a year ago. The stuff i play is heavily influenced by oasis, beatles, coldplay, interpol, dave matthews band, acdc, and other bands/artists. This works very well with my set-up. It sounds unique and it was inexpensive. I've been playing for 5 1/2 years and have always been a fan of the muffs. The Russian Big Muff Pi RI is absolutely amazing. Its nasty, raunchy, fuzz and I love it. Too bad mine broke. Its not that sturdy... and I didnt even drop it or anything. Just a LOT of use. The NYC Big Muff Pi RI is cool. A lot sturdier, but the sound is a little more tame. I prefer the Russian sound to the NYC sound, but the NYC is built better. The Double Muff is built the same as the NYC muff (since it is a NYC double muff..) and sounds just as great as the big muffs. It can be more frustrating since the controls are your standard (gain, vol, tone), but its definitely an awesome pedal on its own. it works well with other od pedals or just by itself. if it were lost or stolen, i'd either get another double muff or the nyc big muff. both are great. i'd probably get the double muff though since it goes so well with my amp. everyone should at least give this pedal a test run. but, i would strongly suggest testing it with an amp that is the same, or at least most similar, to your own.

factoring in the price of this pedal (which is CHEAP) and how much i love this pedal, it gets a ten.

3 knobs and a switch.
Only thing that bugs me is that it doesn't sound very good in
double mode unless you pull the volume to max.
Other than the fact that the guys in my band
don't know shit about how to define sound - I love it.

Fender Strat, Fender Hot rod, boss sd1, wha.

Noisy as hell, but hey - that's the point!

The double-single switch is getting harder to use..
maybe I should clean it once in a while..

Great if you like lots of sustain and if you want to
turn a clean amp into a monster.

Really nice. I didn't find the "single"mode to be as I had expected it at high volume, but it had a really nice "dirty" sound. I've played it on a Orange rockerverb30 combo amp and it sounded great.

How hard can it be with three knobs and one switch?

Really the best fuzz, overdrive and distortion I've owned to date.
The "single"mode sounded more like overdrive or semi-dirty but the doublemode, all knobs full was really awesome.

This is exactly what I have been looking for all these years!

I play a Fender Strat with vintage noiseless pickups and I have a Fender all-tube amp.

Hmm.. I think I will eventually have to replace the on/off button since I often play drunk and there is a risk I'll step too hard on it..

Have'nt dealt with them yet..

I play lots of different styles of music but now, having bought this I'll play nothing but stoner again.

795 kronor (swedish piss-money) ain't too bad for this!

if it were stolen I'd kill to get it back!

Very Straightforward. Although it takes a minimum of understanding to really get the controls straight. It's basically two Muff effects chained together. I always enjoy two Muffs more than just one. Anyways, there's an individual knob to control the output of each Muff, an on/off foot switch and another switch that goes between single Muff mode and dualing Muff mode.

When in single Muff mode, only the Muff 1 control effects the sound. When in Double Muffer mode, both the Muff 1 and Muff 2 dials effect the overall output.

Sound is very good. Especially plugged into a Fender tube amp like i do it. Either Princeton Reverb or Twin Reverb. With one Muff on, it basically acts as a somewhat transparent gain. It gives your guitar a nice clean boost, but if you turn your guitar volume all the way up and the Muff 1 dial all the way up it starts to get into the mild Overdrive territory which can sometimes be a nice territory to be in especially when you are looking for that slightly distorted tube harmonic bliss. When you switch over to 2 Muffs; Two Muffs are always better than one, have i mentioned that before?; You get a real Overdriven distorted sound. But between the two dials for Muff 1, Muff 2, and the guitar's tone and volume control, you really have a lot of flexibility to alter the sound scape between heavily Overdriven and lightly boosted.

One other thing to mention here is that even though this is a Double Muff, it is definitely not a Big Muff. Do you need Double Big Muffs? I don't know, maybe after a night at the bars in some state highway motel. But certainly not every night.

The Big Muff will give you a very long sustain that this pedal is not capable of. With a Big Muff you can hit a note and make it last til sunrise. But this pedal is better for Boost, Overdrive, and distortion, not so much for the endless note.

As for added noise. I don't know, i don't pay attention to that because once you start cranking amps and pedals you inevitably get noise, but if you didn't want noise you wouldn't be cranking in the first place.

I've just recently acquired this goody, so it doesn't have much history with me yet. Maybe i'll update at a future date. But just to tell you, the Double Muff box is made of two materials. The top half is the standard aluminum box that Electro-Harmonix houses their wonderful little sound toys in, while the bottom half is a durable plastic. I'm not going on tour anytime soon so i couldn't give you the full crash test report. But i think it would hold up pretty well.

Don't know.

This is a very nice effect. I haven't put it head to head against a Tubescreamer but i imagine it would hold it's own. It's got a lot of range so you can dial in settings from a clean push on your guitar, to a dirty shove. So the spectrum of sound out of this one little pedal is quite nice. Although if you needed to quickly switch between a clean sound and a distorted sound you'd probably be best to get other stompers since you'd have to bend down quite a bit to vary the settings of this one.

Overall, a very nice pedal, for a very nice analog sound, with a very nice price tag.

The manual is good, tells you to use your guitar volume and tone to mess around and refine the sound, instead of kneeling down and going "Duh, which one is it again"

READ THIS FENDER JAGUAR PLAYERS! READ FOR SETTINGS TOO! The pedal has a very unique "feature" I have never seen before - you know the nigh-on uselss "bass cut" switch on the Jag? Not useless anymore! With the switch engaged, it removes a lot of the distortion from the sound and gives you the option of less distortion and slightly reduced volume at the flick of a switch on your guitar. Watch out when you switch it back on! Also, use your tone control with it - it strips away all the distortion, which you can then re-introduce for your back-arching, teeth-clenched, squealing thermonuclear guitar break. I use it with a peavey Classic 30 Valve amp - one problemino is that it sounds utterly dire with the amp distortion engaged - my Boss DF2 sounded ace in that respect, giving valve OD with a solid state edge. If only it sounded good with your amp distortion...and don't put it after buffered effects like everyone else is saying. It sounds awful, even after the minimal tone suckage of a Boss LS2! It has to go first, which is a minor inconvenience.

Settings:

Creamy high gain distortion that you can then customise on the guitar: > Both muffs on - M1 set to 9 o'clock and M2 to just before 3 o'clock. Use the guitar tone control, volume etc to set the pedal from there. You won't believe how wonderfully sensitive it is. Email me to talk Muffs and share discoveries of the pedal (oo-er, Matron etc)- bilbicus@yahoo.com

Sometimes you can hit the Muff 1 dial with your foot when engaging the footswitch. That can result in seriously embarassing moments when you give everyone a heart attack as your guitar comes in at 5 billion db's. Or, very quietly. Ooops. No probs otherwise.

Never dealt with them - their website could tell you more about the effects. It is a bit thin on information. I have a Micro synth too, and I really like that pedal as well. Getting a Memory man for christmas!

I play in a duo, we do rough rock thru to mellow acoustic stuff. This gives me a True Bypass distortion that is incrediblt versatile. Try it out - it is not for everyone, and takes some time to "get to know".

It's a fuzz doesn't get much easier. Two knobs one switch. It would be nice if EH put volume knobs on thier pedals but it's not a big problem on this one. I leave it on double and use one of the knobs to control the volume from the other one. Mine didn't come with a manual but i t really doesn't need one.

Freakin' awesome. I always liked fuzz. This box will fuzz but not as over the top as a big muff or a fuzz factory but it has just enough for me. Like everyone else I agree, muff 1 sounds like an over drive and muff 2 is a thick fuzz almost a distortion. Overall good fuzz sounds. I had a Maestro but I sold it and bought this on, much better.

It's built out of old Serbian tanks, no maybe not. It does feel very solid.

Any one wanting a good all around fuzz should check this out. Not incredibly versitle but fuzzes usually aren't. I like to play kind of raw indie rock. give me a marshall and some greenbacks and i'm good. maybe with brighter speakers it might be a little earpiercing but with things the way they are it is great. Put it in front of a wah and it will come alive. If it were stolen I would probably get another one or a big muff since they are so similar.

Super easy to use, just cascading distortion.

This thing sounds fat, heavy and thick. I use a Sunn Model T or a Sound City Mark 4 & a Matao (les paul imitation) with Seymore Duncan pickups. You can get a nice soft fuzzy feel or a bundle of hiss out of this pedel, it sounds great! It has a little thicker and heavier sound that the original big muff.

I sent this thing back to Electro-Harmonix twice and it still doesn't work right... The first time I was picking up Japanese radio!?! They fixed that problem but then the LED light would not work, so I sent it back again! They fixed that problem but now there's trouble with the switch, on the double setting... So needless to say I kicked that piece a shit across the room... Funny thing was the next day I pluged it in and it worked great for a couple weeks and then it starting acting up again... So now when it starts acting up I just stomp on it a dozen or so times until it works... Can't depend on it at all and would not ever use it for a gig.
Reliability? NONE!

Great customer support, they even paid for shipping the second time I had it shipped to them for repairs. But the people who do the repairs have got to be retarded one armed monkeys! They fix one problem, and another arises. The last time I had it shipped to them I asked if they would just send me a differant one, they said yes! But when I recieved it, it was the same one! LIARS!

OK this pedel sounds great, I mean really great! But it also is the biggest piece of shit ever made! I have other pedels and amps that are 30+ years old and give me no trouble but this thing really pisses me off! I play really crappy punk or stoner rock for 15 years now. I love a clean amp with a distortion pedel; Rat, Big Muff, Blue Box and Fuzz Face. And this Double Muff sounds just as good as any of those but it only works part of the time.
So if you go and buy one be careful and keep your receipt! Just be warned that this pedel isn't gonna last 30 years let alone 30 days so you might need to but two.
I've been thinking about buying another myself, hopefully I have better luck.

two knobs and step,you get the idea

WITHOUT A DOUBT GREAT PEDAL.I play a Les Paul Classic into 535 dunlop wah,EH dbl muff,Korg tuner infront of a vl-502 ampeg head/marshall 412 cab through ch.1 clean.Through my efx loop I have a boss dd-5,tr-2,dan echo,and a boss super chorus,small stone phase and an ibanez fl9.For a few months now I have been very unhappy with my vl-502 particularly on the dirty side(clean is descent) so I tried this pedal out and was shocked on how great it replaced my ch. 2.You can 70s saturated fuzz on up to thick distortion offers tons more bottom than my Ampeg.For all those that were dissappointed in that it didn't sound like your old Big Muff NEWS FLASH ITS NOT,hence the name double muff, if you want the classic Big Muff sound then uhhhhh.....well play a Big Muff not to hard to figure out.Nice thick rythms and super lead tones......SOLD!

It's Electro-Harmonix no worries here.

Can't say no issues yet

For what I play(emo-core) sounds great and very inexpensive.

The only thing easier than two knobs is one knob. This pedal is cake to use, but wold be more controlable with more knobs. All in al it's simple and yet versitle.

Sound quality is ok. The pedal actually is not very fuzy. In single muff mode it sounds like a slight overdrive - which is really cool. I own a full drive II, and so I am a big fan of slightly gritty sounds. Unfortunately the FDII has the double muff's number - and then some in that department.

Sadly, the double muff never gets very fuzy. I am surprised at some of the reviews here that claim that the double muff can get insane or what ever. Perhaps they have never used a fuzz pedal before...
I have a big muff - which I love - and was hoping the double muff would be even crazier - it's not. Not in the least. It's like a little fragile brother of the Big muff (and perhaps could be renamed "little muff"). I was disapointed. The big muff has fuzz, and sustain and all tat, and has tone and volume controls. The double muff is not as tweakable as the big muff, nor is it as fuzzy. Basically it's a col pedal for doing slightly overdriven sounds all the vay to mildly fuzz distorted sounds. The good thing about this pedal is that it's clear sounding (unlike the big muff which is very muddy)and can produce many interesting (though not realy fuzzy) sounds. I give i a five - it's cool, but certainly no "Double Muff"

Actually the unit seems flimsy and fragile to me. The input jack on mine stopped working and I had to have it replaced as soon as I got it. EH is a funny company. Many of their pedals are built like tanks and many of their pedals are not. Go figure.

Here's the skinny - cool sounds, little fuzz - moderately dependable physicaly. Proceed with caution and don't expect too much fuzz. For big fuzz hit the Big Muff, or a ZVEX fuzz factory.

2 knobs, 1 switch very easy.

Sounds great. It's the tone I've been looking for, and it beats my boutique pedals such as the Zvex FF.
Though it's very different from the FF and doesn't have the variations of fuzz, the tone you do get is excellent and the pedals dead quiet.
I'm running a Tele into an early 60's Silvertone tube amp.
The tone really cuts through and fills out the souind. I compared it with a bunch of my other pedals and it has the best tone. It's not as fuzzy as the Big Muff it's more like OD/fuzz. Sounds more authentic than most modern Fuzz and Dist pedals.

Seems fine so far.

Never needed it.

Very cheap pedal and definately worth having. Easily one of my favourite pedals. I like it so much I might buy 2.

Simple but subtle...

I'm a bass player but I play guitar too... It sound great why my 1969's Gibson EB3 and my Epiphone Firebird (awesome with the MXR Dynacomp before in the effect chain).

I had before a US Big Muff reissue, I think the double Muff works better with a bass.

Not sure, I've had bad surprises with EHX gear...

Style of music : independant rock, dark blues (Morphine, Tom Waits, Mark Lanegan, Primus....). I tried many fuzz and overdrive, it's not easy to get a good distorted sound on bass, this one sounds good for me... great with guitar too, I don't want to spend a lot of money in effetcs so like those which work good both on bass and guitar (other gear : EHX Pulsar, Sansamp Bass Di, EHX Holy Grail, MXR Dynacomp, Morley PWV II custom for bass, RMC1 wah and Boss Tu2)

There is no manual, but it is not needed. Two dials, one switch. Just f*ck around until you find what you want. It's fun!

I have used it with both my two guitars, a Squier fat strat and an old Kasuga hollowbody. It sounds really nice and organic, and not tinny like some overdrive pedals. I always use it with everything to full, you get moderate distortion, a lot of sustain and a lot of volume. I have noticed that muff 1 is more trebly and muff 2 more bassy, so if you turn muff 1 down you get a nice bassy Black Sabbath-esque grind (and vice versa-or it may be the other way round). On single muff, the harder you play the louder and the more drive. It's very versatile. A bit of white noise, but this will always be with distortion pedals.

Extremely reliable, has never failed. The one battery has lasted me 3 months so far, and it doesn't look like it's about to stop now.

Never needed, never used

I play rock/blues and am getting into surf, and this can do everything you throw at it. On single mode it can act as a valve simulator, which is useful as I have a Marshall solid state amp.

Pretty simple but not perfect. The Double Muff is deceptively flexible.

In "Single" mode the amount of fuzz is constant. You use the "Level" control to get your desired volume.

In "Double" mode it can be tricky to balance the two fuzz circuits. You may find it hard to get the distortion sound you want at your desired volume. Can be difficult to maintain a consistent output level when tweaking in a live situation - don't want to drown out the band! However, having the two circuits set up like this is all part of the mojo here! A master volume control would make dialling in high gain settings much easier.

You pretty much have to plug your guitar straight into the Double Muff to get a good sound out of it. This can make it difficult to use with a long effects chain. This is a problem shared by many fuzz units.

Battery compartment must be accessed with a screwdriver :(

I use a Fender Telecaster with a Fender BF Bassman combo. There is a lot of treble in this setup, and I find the Double Muff considerably warms and fattens the sound of my guitar while letting its natural tone through. It also works nicely as a signal boost to give the old amp a kick in the teeth. You can go from a light overdriven sound to very heavy fuzz.

The unit responds extremely well to the dynamics of your playing. In "Double" mode especially you can use this responsiveness to great rhythmic effect. Reducing the volume control on your guitar a small amount will dramatically reduce the amount of fuzz.

Also sounds nice through my solid state practice amp.

True Bypass!

Pretty solid on the outside but I haven't bothered to check out the insides.

Should last a long time if kept in the wooden box provided. No problems so far, but its only been 4 months.

Battery lasts for ages like most effects of this type.

Would get it fixed locally, rather than send to the States. Did come with a warranty card, but its still in the box.

I play all sorts of rhythm guitar and do a bit of noodling, but no major lead work. I have been playing for 8 years. The Double Muff is great for rhythm playing because it is so responsive. It has a warmth about it that I find well suited to the Telecaster.

Lead players will bemoan the lack of sustain.

It has replaced my Vintage Rat mk1, which creates too much treble for my rig.

One obvious improvement would be a master volume control, which would vastly expand its flexibility on high gain settings. The simplicity of this unit lends to the mojo, however.

Would definately replace.

Oh, and it has the word "Muff" written on it THREE times!

seems easy but it's not!
got to be aware of some rules before play with this baby!

see after why I put a 5

Great great great!
but! BUT YOU GOT TO PUT THIS PEDAL AT THE BEGINNING OF YOUR FX CHAIN.
If you don't do that it will sound tinny and crappy.
Put it in the fist position even if you own a wah wah...

You can use it with oither distortion and it's sound gtreat!

The very medium/treble distortion is great to deal with drum and bass. You can hear you through the mess of the band!

electro harmonix pedal are great.

Great good sound. Somewhere bertween ds2 and big muff.

Features: On/off switch, slider for single/double muff mode, two rotary controls for the two Muff Fuzz Circuits. No manual supplied.

N.B. This pedal does not have two Big Muff circuits in series, as I think some people are assuming. It's two Muff Fuzz circuits... The Muff Fuzz was a little gizmo that E-H produced back in the day (it wasn't even a stompbox, just something with an on-off switch!)

With a set-up like that, things should be simple. The two fuzz controls react in a more complicated way than is obvious to begin with, though, and so this pedal can seem a little confusing.

I don't gig, so I don't play through an Amp any more. Usual guitar is a DeArmond Jetstar, played through an assortment of effects boxes, into a Behringer V-Amp, which is frequently hooked up in to my PC for recording purposes.

The Muff is quite a quiet pedal, noise-wise: only with both fuzz controls cranked do I hear buzzes and hums (usually monitor related!).

This is quite a versatile pedal. It's capable of some quite mellow crunch/overdrive sounds, but also of incredibly loud volume and gain boosts. Don't expect to be able to turn the controls randomly and always find a useable sound!

Single muff mode: The Muff 1 pedal acts as a gain control. There's a fixed amount of distortion to be had, but you can dial up unity gain (which gives a really nice crunch sound) or, with the control over halfway, use it as a volume boost that also adds some sustain to solos. It's very responsive to volume and tone changes from the guitar, which is a pleasant surprise!

Double muff mode: Ye Gods. Both Muff controls are now active and interact with each other, giving a huge number of gain and fuzz options.

Turning both up to full will add a huge amount of sustain and far, far too much volume. I can't see any circumstances in which you'd ever want so much of a boost, but it's there if you want to blow the heads off the audience!

A much better idea is to use one control as a gain control, and the other to control the amount of distortion. If you use Muff 1 as the distortion control and max that out, you get a more open, overdrive type sound. Use Muff 2, and you get a much more strongly saturated, Big Muff type sound. Both sounds are as responsive to your guitar's controls as the Single Muff Mode, and they're both really pleasant, useable styles, for most rock applications short of Death Metal.

You can, of course, make fine adjustments to the controls to get a suprisingly wide range of distortions. I find it very easy to dial up a good sound, indeed I would rate this as one of my favourite distortion pedals.

As others have noticed, it does like to be first in the pedal chain. I have put a compressor behind it successfully (an old 80's Vesta Fire), but if you put it after most buffered pedals, your tone will suffer.

Very dependable, seems very well fixed together, with quality parts and workmanship. I'm not one to jump on my pedal board, so maybe I don't give pedals the hardest workout!

Bought from Music Ground in Denmark Street, London, who are by far the most helpful shop in that area. Never tried to deal with E-H - if there were any problems I would go back to the dealer first.

I'm very happy with this pedal. It's not a Big Muff (that's next on the shopping list) but what you lose in sustain and fuzz you gain in verstility. The Big Muff is one of the most "effect-y" pedals, in that it dominates the sound when it's on, but the Double Muff is a lot more transparent, and allows your guitar and amp to shine. It's versatile but distinctive, and I can find lots of inspiring sounds when I'm using it. It's quirky (it's E-H, what do you expect!) but effective, and at #50 there's nothing to beat it for the price.

gain 1 & 2, very easy, but requires some balancing as gain 1 can have a large effect on your volume, just has to be finessed.

I use this primarily with a couple mid & high gain settings with a mesa amp. It gives enough gain to push the amp over the edge of insanity into pure face melting, if you like that sort of thing. I also really really like the way it sounds in front of an EH micro synth; dirtys everything up a little. I haven't found a use for it through clean channel yet, but I will. It is a little noisy and in conjunction with a high gain amp it can feed back like mad, an MXR smart gate goes most of the way to making this dealable.

The first one I got had a bum switch, the dealer replaced and it's been humming along ever since.

haven't dealt with them

Overall, I love the sound, it's organic and throaty. Compared to the only other distortion pedal I know well, the mxr ditortion+, it's less containable, but you're paid back with tone.
