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.
