Big Muff Pi 2 resurrects lost dual op-amp fuzz circuit

Electro-Harmonix just brought a lost Big Muff design to life after JHS Pedals guy Josh Scott and artist Daniel Danger dug up an old schematic that creator Bob Myer never actually produced back in the late seventies. The Big Muff Pi 2 runs on dual op-amps instead of the usual transistor setup, and Scott helped EHX turn the dusty blueprints into an actual pedal people can buy.

The circuit supposedly pushes less gain than other Muff versions but pumps out fat lows and thick mids with ridiculous sustain. Standard three-knob layout handles distortion amount, tone shaping, and output volume on a tiny nano chassis with relay-based true bypass that works in both latching and momentary modes.

Runs on nine volts through battery or adapter, ships with the battery but no power brick.
