Originally, the Echoplex was a device for achieving delay effects. It's well-known that it was used as a preamp for purposes like "making the sound thicker" and "tightening the sound," but its size and maintenance issues made it less appealing. The Xotic EP-Booster was created to easily obtain this warm and full preamp sound. Using top-quality parts, it's designed to withstand the demands of professional players. It's even more compact than conventional compact effects pedals, adapting to the trend of slimmer equipment in recent years. The EQ characteristics can also be changed with the internal dip switch. The simple one-knob design is focused on sound that can be used immediately upon connection.
