The Super Badass Variac Fuzz is a dream come true for guitar players chasing vintage fuzz tone. This tasty fuzz is aggressive and biting, and with the twist of a knob, you can drag it into that dying battery territory much prized by tonechasers-no need to manage a collection of half-dead batteries.To create the Super Badass Variac Fuzz, the MXR design team dusted off a rare vintage silicon circuit, tuned it up, and added a Variac control so you can set the pedal''s voltage anywhere from 5 to 15V. For that wonderful saggy fuzz effect you get as a 9V battery loses its power, just lower the voltage by turning the Variac knob counterclockwise. Increasing the voltage raises the effect''s headroom, opening up the fuzz for a more transparent sound at 15V.The Super Badass Variac Fuzz''s simple interface is rounded out with Tone, Output, and Gain controls, and it all comes in a road-ready housing with true bypass switching. Specifications Input Impedance: 300 kO Output Impedance: 120 kO Variac Range: 5 to 15 V Noise Floor*: -98.5 dBV Current Draw: 17 mA Power Supply: 9 volts DC WATCH: MXR Super Badass Variac Fuzz
