Introducing the Electro-Harmonix Op-Amp Big Muff Pi - a faithful reissue of the coveted late-'70s classic, designed to deliver the iconic fuzz effect at a pocket-friendly price. This compact pedal leverages op-amps rather than transistors and three gain stages instead of four to generate its signature sound. Adored by many, including Billy Corgan of the Smashing Pumpkins, the Op-Amp Big Muff was a significant component of the band's unique sound in their 1993 album, Siamese Dream.

This reissue retains the magic of the original while being encased in a robust, die-cast chassis. It also incorporates practical enhancements such as true bypass switching, preserving your tone when the pedal is not in use. The controls for volume, tone, and sustain allow you to quickly dial in the fuzz-laden and explosive textures your music demands. An additional tone bypass toggle temporarily circumvents the pedal's tone circuit for maximum output and aggression.

• Faithful reissue of the late-'70s op-amp Big Muff Pi
