Few can deny the effect pedals such as the Big Muff fuzzbox have had on the sound of the guitar from its initial design in 1969 to this day. Its bass-heavy sustain, designed to mimic the fuzz tones of Jimi Hendrix would revolutionize fuzz in the sounds of many legendary players in the course of its life. Carlos Santana, David Gilmour, Metallica, KoRn, Jack White, The Edge, Billy Corgan would join the list of names whose sound the pedal became fus(zz)ed with. The band Mudhoney even titled their debut EP “Superfuzz Bigmuff”.

Founded in 1968, Electro-Harmonix was the brainchild of partners Mike Matthews (rnb keyboard player) and Robert Myer (electronic engineer) who set out to design a circuit which would create a distortion-free sustain ‘fuzz’, that was so popular at the time. The Axis fuzz pedal, sold under the name ‘Foxey Lady’ as a reference to Jimi Hendrix’s sound on the famous track and the Linear Power Booster (LPB-1), a simple line booster used by Matthews in testing to pre-amplify the guitar’s signal were the first pedals to go on the market. The LPB-1 massively boosted guitar signal to provide gain by clipping the signal, resulting in a raw, distorted sound, full of sustain and harmonics.

After a brief pause between the mid-80s and early 1990’s to develop re-branded vacuum tubes, Electro-Harmonix set to work with re-issues of their most popular models. It wasn’t till 2002 that their ever-expanding range of new models and pedal-combos began to emerge and further shape the sound of many of the industry’s most venerated musician’s sounds and processes. The Small Stone phase shifter would shape the sound of Jean-Michel Jarre, The Electric Mistress analog flanger; integral to guitar legend John Frusciante’s timbre. The Memory Man delay pedal was used by The Edge in “Sunday Bloody Sunday”. Electro-Harmonix pedals can be found everywhere in your favourite records and offer a wealth of creative possibility in crafting a unique sound.

Big Muff Pi V4 (1977).png

The Smashing Pumpkins fuzz. The Electro-Harmonix Big Muff has had many versions during its lifetime. The unit we have here is the V4 one which is associated with Billy Corgan of the Smashing Pumpkins. The unit uses the EH-1322 board and is all stock. As to sound, try it out for yourself using the TonePedia player, compare it to other models too. The EHX Big Muff Pi V4 was in production for approx two years, so it is relatively hard to find.

Electro-Harmonix Big Muff V7c (1994)

The Famous Green Russian This pedal has been one of the most talked about fuzzes of recent years due to its unique aggressive tones.The back story to the pedal is very much the Phoenix from the flames proverb, EHX had gone, the soviet union too had gone but people needed to carry on. Mike Mathews saw renewed love for his original big muffs and saw that Russian manufacturing was cheap and born from this was the Russian Big Muff. So rare and so popular now, they have become the new pedal which every company creates their own version of. Compare it with the many other Big Muffs and variants of to see if you think it deserve the hype!? 

Electro-Harmonix Memory Toy

Not a toy! The Memory Toy presents a pure analog delay for musicians who covet thick sound from a thin wallet. EH melds heritage with select components to present the musician with up to 550ms of delay. Not a toy but a professional tool that bathes your axe with organic depth and dimension. The selectable chorus is a lush bonus. No one does analog like Electro-Harmonix!

Big Muff Pi, a tick smaller. If you like the Electro-Harmonix Big Muff Pi but prefer a little bit smaller enclosure, then the Little Big Muff Pi is what you need. Electro-Harmonix promises that the Little Big Muff Pi sounds exactly like the original Big Muff Pi so there are no down sides to this down-sizing. Load both to the TonePedia player and see how similar they are. Sound wise what is there to say?! The Big Muff is a rich fuzz / distortion pedal that delivers violin-like sustain. It is one of those pedals that shaped the face of Rock and Roll. If you need a much smaller version of the Big Muff Pi, check the Nano Big Muff Pi which can also be found on TonePedia.

Electro-Harmonix Big Muff Op-Amp
Big Muff Op-Amp.png

Big Muff With Butterfly Wings In the 70's the standard big muff circuit underwent various changes and towards the end of the decade the Big Muff V4 was born. These hold a special place in the heart of many, partially due to the raw saw tooth like clipping which somehow manages to keep clarity. For many this pedal was more like an overdrive/distortion and people began using it to emulate bands like the mighty Black Sabbath. Exactly that path took a young band in the 90's down the same road. The Smashing Pumpkins wanted the Tony Iommi tone and after hearing big muffs in use the knew this was how to do it. From there they went on to record one of the greatest albums of the 90's Siamese Dream and as a result the Op Amp Big Muff became "that sound" Tell us, do you think its the best of the muffs?

Electro-Harmonix #1 Echo

An ultra great delay pedal for the ones who like to keep it simple. Electro-Harmonix has a reputation for quality delays and the #1 Echo is a prime example. The tone is ultra high quality up to two seconds of maximum warm analog-sounding delay. The feedback control sets number of repeats and how fast they fade. The blend control lets you adjust the balance of echo volume with straight through signal, putting your sound exactly in the pocket you want.

A huge tone in a mini pedal! The Electro-Harmonix Russian Big Muff from the '90s became a hit shortly after being released. the growling low ends, full on fuzz it delivers has such a distinct character that after all these years, it is still sought after. The Mini version of the green Russian Big Muff is based on the Tall Font Sovtek version from the mid '90s. This pedal roars all the way! Do not expect germanium-like cleanliness from it, it is a beast. We find the Electro-Harmonix Green Russian Big Muff musical. The switch from the slicing fuzz to a smooth distortion is smooth, and the tone control really comes handy. Load it and some other Big Muff versions onto the player to find the right one for you.

Electro-Harmonix Big Muff V6 (1979)
EHX Big Muff V6.png

The Muff with Many Faces We assume that by reading this you know that an EHX Big Muff is the best selling Fuzz pedal of all time and that many different variations exist. We'd also assume that most people reading this aren't exactly clear on what those differences are and are looking for a little further clarity. Based on that, you've come to the right place ... kinda!? The reason for the hesitation is this, there are many versions of the Big Muff, (V1,2,3,4,5,6 and so on) within those we have other lines such as "The little Big Muff" etc. And if it were that clear then life would be easy however within variations such as the Version 6 Big Muff components changed on a whim, as did the designs. Most V6 Muffs used the large black "Hockey Puck" style knobs where as a few used the Daka Ware pointer knobs as seen on the much earlier Muff Versions. Most strikingly the often named "Reverse Logo" Muff was black with a white logo and Pi sign featuring a large red area by the foot switch, however many were in the standard famous unpainted enclosures featuring the normal red logo and Pi sign with a black area by the foot switch. The V6 saw a mainstream return to the transistor based circuit and sounded much closer to the version 3 Muff. Despite the appearance variations the V6 was the first Muff to see all versions using the same schematic. This led to most V6 Muffs sounding constantly the same, that tone being like the V3's but with more gain/sustain on tap and more grit in the break up. The tone bypass switching borrowed from previous versions took the tone out of the circuit giving more clarity and a boost in volume and midrange however it does sound much less "muffy" in this mode. Often an overlooked member of the Muff family in favour of its older op amp brothers this is still a stand out pedal which if you find you should lay your hands on ... we did. 

Electro-Harmonix Big Muff V3 (1977)

Is this the most iconic Muff of them all? The Version 3 Big muffs (1976-79) were the first muffs to have an AC power in and some featured a tone bypass switch. Looks wise the now familiar red and black paint job featuring the Pi symbol was used. The very first V3's however had none of this, no Ac Jack, no tone bypass and in fact the circuit was exactly the same as the V2 Big Muff ... And THAT is what you're experiencing with this pedal.  Featuring the BC-239 transistors and the exact circuit in a V2 Ram's head edition this rare muff certainly is a nice piece of Pi.

Electro-Harmonix Triangle Big Muff

A reissue of the one that started it all. The Electro-Harmonix V1 "Triangle Big Muff" (called after the layout of its knobs) was originally released to the market somewhere towards the end of the '60s. It made waves! This pedal was used on countless of records, you can here it played by Santana, David Gilmour, Steve Howe and more great guitar players. In 2018 EHX reissued this V1 Big Muff and named it the Triangle Big Muff, they claim it is a faithful reproduction of the V1. While we cannot compare it to the original, we can definitely say that the Electro-Harmonix Triangle Big Muff is a magnificent distortion which delivers heaps of sustain and tone. It is one of these pedals where you really should read about less and play with more so add it to the TonePedia player and find out what it is all about.

Electro-Harmonix Flatiron Fuzz

EHX's take on the RAT One of the most iconic distortion pedals out there is the ProCo RAT, it shaped music as we know it and as such, many pedal builders out there came out with their clone or version of a RAT based pedal. The op-amp powered Flatiron by Electro-Harmonix is exactly that. EHX took the time to research and build their version of the RAT 2 and if you ask them, they are confident that their Flatiron surpasses the original. This symmetrical fuzz/distortion features a simple, three control layout. While Volume and Drive are self explanatory, the Filter knob is somewhat unique to the circuit and acts as a low pass filter. How does it compare to the classic RAT you ask? load both to the player and hear for yourself.
