Capture the authentic sound of the classic 1969 Muff Fuzz without having to sell your kidney via this reissue from Electro-Harmonix. The Muff Overdrive is a no-nonsense overdrive guitar effects pedal; you get a footswitch and a volume knob to dial in the worn but warm speaker-style overdrive of a vintage tube amp. The Muff Overdrive comes in a rugged, pedalboard-friendly die-cast aluminum chassis and can be powered via a 9V battery or a compatible power supply.
