MF-4 Fuzz

The MF-4 is a fuzz pedal based on the Green Russian and NYC Big Muff circuits, modified for heavier tones and increased control. It delivers high sustain and aggressive fuzz while retaining a tight low end and enough clarity for both guitar and bass. Its expanded Mid control addresses the characteristic mid scoop of traditional Muff-style circuits, allowing the response to range from deeply scooped fuzz to a more prominent, full-bodied midrange sound. Designed for heavy styles such as doom, sludge and stoner rock, the MF-4 combines classic Muff-derived fuzz characteristics with greater control over how the pedal sits in a mix.
