The MXR Fat Sugar Drive brings the Sugar Drive’s diverse range of clear and transparent overdrive tones to MXR’s classic housing for players who prefer its footprint over that of the mini. This pedal is powered by one 9-volt battery (accessed via underside of pedal), the Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies.
