Based on Electro-Harmonix® Big Muff Pi®
In 1969, Bob Myer and Mike Matthews designed the Big Muff Pi, a fuzzbox that added a bass-heavy sustain to any guitar sound. It is described by the company as “the finest harmonic distortion-sustain device developed to date”. Originally this was intended to be a pedal that would mimic the fuzz tones of Jimi Hendrix and other guitarists at the time, but the result was a mix of a fuzz and distortion pedal with a very heavy sound. It also made small amps sound much better and allowed distortion at any volume.
The pedal sold well and was used by Carlos Santana, Pink Floyd’s David Gilmour, Alex Lifeson of Rush and, later, Metallica’s bassist Cliff Burton, The Jesus and Mary Chain, and in the 1990s KoRn’s rhythm guitarist Munky, Jack White of The White Stripes, J Mascis of Dinosaur Jr., The Edge of U2, and Billy Corgan (on The Smashing Pumpkins landmark album, Siamese Dream). The band Mudhoney titled their debut EP Superfuzz Bigmuff.
