Used Electro-Harmonix Big Muff Op-amp Effect Pedal

Unleash classic ’70s sustain with this used Electro-Harmonix Big Muff Op-Amp fuzz in great condition. Famous for its aggressive, cutting distortion and singing lead tone, it delivers massive gain with tight low end and smooth sustain. Simple, gig-ready controls include Volume, Tone, Sustain, plus an on/off Tone Bypass switch for a raw, mid-forward punch. Standard 1/4" input/output with true-bypass switching and 9V DC power (center-negative) keep it pedalboard-friendly.
