Electro-Harmonix Deluxe Big Muff Pi 1978

This vintage unit from 1978 is a standout piece of analog history, featuring the specialized EH1330A circuit board. It combines the iconic op-amp fuzz saturation of the late seventies with an integrated compressor circuit for unparalleled sustain and note leveling. The interface includes dedicated controls for compressor threshold and volume, along with a blend switch that allows for complex parallel signal processing. It is housed in the classic large chassis and represents a highly versatile evolution of the traditional muff circuit, offering everything from thick violin-like leads to aggressive percussive textures.
