The Echoplex Preamp recreates the EP-3's legendary preamp mojo, following the same signal path with FET circuitry and a Gain control for up to +11dB boost. 

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).
