Used Electro-Harmonix Big Muff Op-amp Effect Pedal

Used Electro-Harmonix Big Muff Op-Amp fuzz pedal in great condition, delivering the legendary ’70s-style Op-Amp sustain with aggressive mids and smooth, singing lead tones. Simple, gig-ready controls include Volume, Tone, and Sustain, plus a Tone Bypass switch for a rawer, more direct fuzz voice. Standard 1/4" mono in/out, rugged compact enclosure, and powered via 9V DC (center-negative) or 9V battery for easy pedalboard integration.
