ThunderVolt Pedals ‘78 Op Amp Fuzz (Big Muff Clone)

A meticulously hand-built, Vero-board clone of the legendary 1978 Op-Amp Big Muff. Radically different from traditional transistor Muffs, this circuit uses op-amps to deliver a crushing, wall-of-sound fuzz that defined the grunge and alternative rock eras.

 Tone Bypass Switch: We added a custom toggle that completely bypasses the tone stack. Engaging this switch restores all the mid-range and adds a massive volume boost, guaranteeing your solos will cut through any mix.

 100% Hand-wired on Vero board using premium components.

 True Bypass switching for transparent tone when disengaged.

 The definitive Siamese Dream tone in a pedalboard-friendly enclosure.
