The MXR Blue Box by Dunlop is an octave fuzz pedal that drops the guitar signal two octaves down and combines it with gnarly fuzz for huge subterranean tones. It features a simple two-knob design consisting of Blend and Output controls. The Blend knob allows control over the balance between the octave and fuzz effects, while the Output knob controls the output volume of the pedal. The pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included). The pedal is designed to be compact and rugged, suitable for live performances.
