The Dyna Comp Mini Compressor combines the best of classic tone and modern convenience in a housing that's nearly half the size of the original. Thanks to its rare CA3080 "metal can" integrated circuit (IC), this pedal yields quieter operation, greater transparency, and increased dynamic range. An all-new Attack switch toggles between slow and fast attack times. This pedal can be powered by a Dunlop ECB003 9-volt adapter, or the DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included).
