MXR M236 Super Badass Variac Fuzz Guitar Effects Pedal Review (May 2024)


Last updated on May 29, 2024 11:04 am Details


In this review post, we’re going to be discussing the MXR M236 Super Badass Variac Fuzz Guitar Effects Pedal, including an overview of its unique features.

Product Description

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 tone chasers-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.
