MF-4 Fuzz

The MF-4 is a Big Muff-style fuzz that draws on two of the most sought-after versions of the circuit, the Sovtek Green Russian and the New York City Muff, in one pedal. Four controls set it apart from a stock Muff: Level, Gain and Tone handle output, sustain and the treble-to-bass balance, while an added Mid knob restores the midrange the classic scooped Muff voice loses, letting notes cut through a loud band instead of disappearing. That makes it as useful for cutting doom and stoner riffs as for the wall-of-fuzz settings the Muff is known for. It runs on 9V center-negative from an isolated supply, draws 45mA, and uses true-bypass soft switching.
