Big Muff

Original production (1969–1984)

Following the success of the Rolling Stones' hit "(I Can't Get No) Satisfaction" and its fuzz-heavy guitar riff, multiple manufacturers began making transistor-based fuzz pedals. Mosrite rebranded its own Fuzzrite as "the Foxey Lady"—a reference to the song "Foxy Lady" by the Jimi Hendrix Experience—in 1967 for production by Mike Matthews on behalf of the Guild Guitar Company.^[1] With the success of the Foxey Lady, Matthews founded Electro-Harmonix in 1968 to manufacture new designs. This included the dual-transistor Muff Fuzz early in 1969, so named for its muffled sound.^[3] The four-transistor Big Muff Pi model, co-designed with Bob Myer,^[3] followed by the end of the year. Matthews first sold Big Muffs to Manny's Music in New York City, where Jimi Hendrix was among the first artists to purchase one, and it became a major success for Electro-Harmonix.^[1]

These early Big Muffs are known as the "Triangle" versions due to their triangular control knob layout. They used a plain metallic case with black letters. This was updated in 1973 with red, blue, purple, or black graphics and included a ram's head motif in the bottom-right corner. This redesign also used a larger case. In 1976, the outward design changed again to red and black graphics that would become standard in later production runs.^[1] During this time, many notable guitarists used Big Muffs, including Carlos Santana and David Gilmour of Pink Floyd. In the late 1970s, Electro-Harmonix explored a circuit redesign in which the standard model's four transistors were replaced with two op amps, resulting in a different sound and becoming known as the Op Amp Big Muff.^[2]

By the early 1980s, Electro-Harmonix was struggling due to competition from Japanese imports as well as component shortages and filed for bankruptcy in 1984.^[3] The Big Muff remained popular, however, despite the end of the company. It inspired the title of Mudhoney's 1988 debut EP Superfuzz Bigmuff, and had earlier been used for the name of Depeche Mode's instrumental "Big Muff" off of their 1981 album Speak & Spell.^[4]

Sovtek and EHX's return (1992–present)

With the end of the Cold War, Matthews sought business opportunities in Russia, where he founded Sovtek, which became a major supplier of vacuum tubes to amplifier brands like Marshall, Fender, and Mesa/Boogie.^[3] Sovtek's success allowed Matthews to buy back the Electro-Harmonix name and take advantage of the growing vintage gear market, on which original Big Muffs were selling for significantly more than the new prices had been.^[1][3] Matthews turned over the Big Muff design to a small, Russian military factory, which re-engineered much of the pedal, resulting in more emphasis on bass and midrange frequencies.^[2] Released in 1992, this version was dubbed the "Civil War" Big Muff, and "Green Russian" and "Black Russian" variants followed. Lee Ranaldo and Thurston Moore of Sonic Youth both preferred this Sovtek version.^[5] Into the mid-1990s, the Big Muff became an integral part of the sound of many alternative rock bands, including the Smashing Pumpkins, Dinosaur Jr., NOFX, and Bush. In 2000, Electro-Harmonix resumed production of the Big Muff in the United States with the Big Muff Pi NYC Reissue, which was a revised take on a late-1970s model.^[3]

Aside from the standard Big Muff, Electro-Harmonix has made new iterations of the pedal, like the Nano Muff; the Metal Muff, which has a 3-band EQ; the Little Big Muff, a smaller variation of the standard model; and the Deluxe Big Muff. Signature editions of the Big Muff have also been released, such as the Mogwai Big Muff, named for the Scottish band Mogwai,^[6] and a signature model for J Mascis. Reissues of older Big Muff versions include the original "triangle" Big Muff, as well as the Ram's Head, Op Amp, and Green Russian Big Muffs.^[2][7]
