Electro-Harmonix Op-Amp Big Muff Pi - Vintage Op-Amp Circuit Revived
The Op-Amp Big Muff Pi brings back the classic late-1970s op-amp version of the Big Muff with its distinctive harmonic sustain and smooth fuzz character. Redesigned in a compact Nano-sized enclosure, this pedal delivers the iconic tone players love while fitting easily on modern pedalboards.
Simple Controls, Iconic Sound
With just three knobs for Volume, Tone and Sustain, the Op-Amp Big Muff gives you quick access to thick fuzz textures, swirling sustain and soaring lead tones. A one-switch Op-Amp On/Off toggle lets you select between the original discrete transistor circuitry or the modern op-amp version for tonal variation.
Stage-Ready Build, Pedalboard Essential
Housed in a rugged die-cast enclosure with true bypass switching, the Op-Amp Big Muff is built for live use. Powered by either a 9 V battery or standard 9 V DC centre-negative adaptor, it draws approximately 15 mA of current and fits comfortably on tight boards.
