Seller's description

Dial up huge walls of grungy sound, searing lead tones, and much more with this modern version of a classic Big Muff pedal. The circuitry of the original Op-Amp Big Muff (sometimes referred to as the IC or V4 Big Muff) has been faithfully recreated, while several practical enhancements have been added, including a compact, die-cast chassis and true bypass switching. The pedal relies on op-amps rather than transistors and three gain stages rather than four to create its signature sound, which is a huge, crushing Big Muff sound with more crunch.
