Check Best Price on Amazon


Op-Amp Big Muffs from the late ‘70s may be selling for about half a kidney right now, but you can still get that massive, crushing Big Muff sound for way less via the Op-Amp Big Muff Pi. This compact and affordable reissue uses op-amps rather than transistors to create that signature crunch popularized by Smashing Pumpkins’ Billy Corgan and James Iha on the Siamese Dream album. Control the fuzz texture via dedicated Volume, Tone, and Sustain knobs and use the tone bypass toggle for maximum aggression.

Details: With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new Op-Amp Big Muff “sometimes also referred to as the IC or V4 Big Muff” has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching. “The Op-Amp Big Muff was popularized by the brilliant Billy Corgan who first used it on the Smashing Pumpkins epic 1993 album Siamese Dream. After he was videotaped playing and talking about the reissue, Billy stated: The magics still in the box, I can still get what Im looking for!” – Mike Matthews The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. Its a sound thats been described by noted Big Muff collector and historian, Kit Rae, as: “a huge, crushing Big Muff sound with more crunch” great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads.”
