In the words of Dunlop:This Fuzz Face Mini Distortion nails the aggressive, biting fuzz tone Jimi Hendrix used at some of his most iconic live performances, with a status LED, AC power jack, battery door, and mini housing for modern convenience.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).
