The MXR Octavio Fuzz brings the iconic octave-up fuzz effect — made famous by Jimi Hendrix — into the standard MXR lineup for the first time. Its touch-responsive silicon saturation produces searing, synth-like tones that respond directly to your picking and plucking dynamics, making it equally at home with straight-up rock players and heavier, slower styles. The layout is deliberately simple: set the Output and Fuzz controls to your preferred volume and intensity, then let your playing do the rest.
