Used Electro-Harmonix Op-Amp Big Muff Pi Effect Pedal

This used Electro-Harmonix Op-Amp Big Muff Pi fuzz pedal comes in great condition and delivers the massive, wall-of-sound distortion that defined the alternative rock sound of the late nineties. Proudly made in the United States, this compact unit utilizes an op-amp circuit rather than transistors to provide its signature crushing gain and sustain, making it a powerful addition to any guitarist's pedalboard setup.
