1980 Electro-Harmonix Big Muff

This is a vintage 1980 Electro-Harmonix Big Muff EH 3034 electric guitar effects pedal. Though the original box for this V6 EH Big Muff has an “EH 3003” model designation on the side, this early V6 Big Muff actually has an EH 3034 circuit. This examlpe is very clean, it works perfectly and it sounds incredible!
