MXR Blue Box Fuzz Pedal

The Blue Box Octave Fuzz drops your guitar signal two octaves down and combines it with gnarly fuzz for huge subterranean tones.

This 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).
