MXR Dunlop Silicon Fuzz

MXR · pedal

The MXR Dunlop Silicon Fuzz is a silicon transistor-based fuzz pedal from MXR and Jim Dunlop delivering the bright, cutting, consistently aggressive character of silicon fuzz transistors. The silicon circuit provides temperature-stable, reliably consistent fuzz performance that contrasts with the warmer but less consistent germanium alternative. Suited to classic rock, psychedelic, and lead playing where consistent bright fuzz character is the primary sonic goal.
