A lost circuit reborn: the Big Muff legacy lives on
Electro-Harmonix founder Mike Matthews and circuit-bending mastermind Bob Myer share a history that shaped the fuzz world. Together, they created the original Big Muff and collaborated throughout EHX’s storied past. Bob, always pushing the sonic envelope, frequently brought Mike fresh designs to match the evolving tech of the times. Some concepts made the cut; others were shelved and forgotten. One such design was the Big Muff Pi 2’s dual op-amp circuit, which had been tucked away in Bob’s files since the late 1970s. Decades later, during an interview in Bob’s workshop, EHX devotees Josh Scott of JHS Pedals and Daniel Danger unearthed the hand-scrawled schematic among Bob’s old notes. Josh decoded the design and brought it back to life as the Big Muff Pi 2 — a lost circuit reborn for a new generation of fuzz fanatics.
