The Silicon Fuzz Face Mini FFM1 Distortion is based on a 1970 Fuzz Face known for its bright and aggressive Fuzz Face sound delivered by matched BC108 silicon transistors. The Fuzz Face Mini pedal series features Fuzz Face tones in smaller, more pedalboard-friendly housings with new features such as a bright status LED, AC power jack and a convenient battery door. As with the original models, Fuzz Face Minis feature true bypass switching.
