The Electro-Harmonix story is long and complex with more untold stories beneath the surface than most could imagine. Part of that untold story is all of the pedal ideas that never got made for one reason or another. EHX aficionados Josh Scott and Daniel Danger had been digging through all of the EHX’s history when they came upon an old schematic at the home of original Big Muff Pi designer, Bob Myer. Initially passed over by EHX Founder, Mike Matthews, for what would become the Op-Amp Big Muff Pi back in the late 70’s, this schematic serves as a window into that untold story of forgotten pedals, so Josh went to work to bring this circuit to life in collaboration with Electro-Harmonix. The result, a Dual Op-Amp fuzz that’s very much Big Muff with its own character dubbed the Big Muff Pi 2.
