“This unreleased circuit, hidden for decades, represents an alternate, previously unknown branch of Big Muff development”: Electro-Harmonix and JHS Pedals team up to release a “lost” Big Muff

JHS Pedals x Electro-Harmonix Big Muff 2: This limited edition fuzz pedal was created from a long-lost blueprint that was unearthed while researching the upcoming book about the NYC pedal brand.

Guitar effects pedal heavyweights Electro-Harmonix and JHS Pedals have joined forces for an all-new Big Muff fuzz pedal based on a long-lost circuit that had been lying around “buried in dust and time” for nearly 50 years.

All things considered, the Big Muff 2, so-called because it features not one but two op-amps, is something of a miracle. Josh Scott, JHS Supremo, chanced upon this lost schematic in 2021 when researching for a book he is co-writing with his friend and EHX über collector Daniel Danger, alongside writer/historian Dan Epstein.
