The EP Booster by Xotic Effects is a pedal inspired by the legendary EP-3 echo machine used by renowned guitarists like Page, EVH, and Johnson. With a discrete FET design and low impedance output, it offers up to +20dB of boost with shimmering highs and lows. Internal DIP switches allow for customisable boost frequencies and EQ settings. True bypass ensures signal integrity when switched off. Can be powered by 9V battery or AC adaptor (optional).
