With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new Op-Amp Big Muff —sometimes also referred to as the IC or V4 Big Muff— has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.

- A faithful reissue of the original classic circa 1978

- Iconic sound and vibe that’s coveted by guitarists

- Controls for Tone, Sustain and Volume, plus a Tone Bypass switch

- True bypass switching for maximum signal integrity in bypass mode

- Rugged, compact, die-cast package…pedalboard friendly

- 9-Volt battery included, also accepts optional EHX 9.6VDC-200mA power supply

- Current draw: 5mA @ 9VDC

- Dimensions in mm: 70 (w) x 115 (l) x 54 (h)
