Used Electro-Harmonix Big Muff Op-amp Effect Pedal

Used Electro-Harmonix Big Muff Op-Amp in good condition, delivering the classic op-amp fuzz sustain with rich, cutting mids—ideal for soaring leads and thick rhythm tones. Simple, stage-ready controls for Volume, Tone, and Sustain make it easy to dial in anything from gritty bite to massive wall-of-sound fuzz. Built in a compact pedalboard-friendly enclosure, it runs on standard 9V DC power and provides true bypass switching for a clean signal when off.
