With original late-'70s Op-Amp Big Muffs commanding 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 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.

• Free shipping
• 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
• Ships with a 9Volt battery, also accepts an optional EHX9.6DC-200 AC Adapter
