Xotic EP Booster

What do famous guitarists like Page, EVH, and Johnson all have in common? They all used the legendary EP-3 echo machine as a preamp. We've captured that magic in this new stompbox, the EP Booster. We used the highest quality components available with a FET design and a low impedance output. The EP Booster provides up to 20dB of pure boost, without fatiguing the ear. Internal switches allow you to choose the Boost frequencies and EQ settings. Features True Bypass to eliminate interference when off. Can be used with AC adapter or with 9V battery.
