By EHX:

The Electro-Harmonix Op-Amp Big Muff Pi faithfully recreates the iconic late-1970s Op-Amp Big Muff, also known as the IC or V4 Big Muff. Originally made famous by Billy Corgan of the Smashing Pumpkins, this legendary fuzz pedal delivers the huge, crushing distortion and sustain that guitarists have loved for decades.

With vintage original Op-Amp Big Muffs now commanding high prices, Mike Matthews and Electro-Harmonix brought the classic circuit back in an affordable, modern reissue. The pedal uses op-amp circuitry and three gain stages to produce its distinctive, aggressive Big Muff tone, ideal for grungy wall-of-sound distortion, heavy rhythm guitar and soaring lead tones.

The EHX Op-Amp Big Muff Pi combines its vintage-inspired sound with practical modern features, including a compact die-cast metal enclosure, true bypass switching, and a pedalboard-friendly design.
