The Dunlop MXR Hybrid Fuzz Effect Pedal combines the snarling aggression of a silicon transistor with the smooth warmth of a germanium transistor to generate a broad range of classic Fuzz Face Distortion tones. With just Output and Fuzz controls, you can create searing psychedelic sounds from the '60s or desert riffage with ease, and it even responds to your guitar's volume control. Get classic and modern fuzz tones in one pedal.
