Electro-Harmonix Big Muff Pi 2 Dual Op-Amp Fuzz

The Electro-Harmonix Big Muff Pi 2 Dual Op-Amp Fuzz resurrects a long-lost Big Muff circuit design from the late 1970s, originally conceived by EHX founder Mike Matthews and legendary engineer Bob Myer. Unearthed decades later and carefully decoded, this unique dual op-amp fuzz delivers a rawer, more aggressive take on the classic Big Muff sound. With singing sustain, massive low end, and a crisp, edgy top, the Big Muff Pi 2 offers a distinct voice within the Muff family.
