The MXR Brown Acid Fuzz delivers psychedelic silicon saturation to guitar and bass players who like it low, slow, and heavy. Based on a classic 1970s UK fuzz circuit, this pedal’s simple three-knob interface allows you to plug in and tune out in no time at all.
Dial in the Output, Tone, and Fuzz controls to set the mood, and then let the heaviness flow forth as the world around you melts into a fuzzy, synesthetic convergence of colors and sounds. Whether you want to ride droning power chord currents across the universe or summon burly grooves at an ancient altar, this pedal has all you need for your musical invocations.
A limited edition offering, the MXR Brown Acid Fuzz comes adorned with the arcane renderings of legendary Bay Area artist Alan Forbes.
