ABOUT THE PRODUCT
Electro-Harmonix has reissued their late-1970s era Op-Amp Big Muff Pi. Sometimes also referred to as the IC or V4 Big Muff, the original circuitry has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.
