The PEPBOOST Pocket Booster Effect Pedal for Guitar from Palmer is for guitar players wanting to add more gain and versatility to their sound. It can be used to increase the volume of an anemic amp, or slam the front end for more overdrive. Built with one 1/4" input and one 1/4" output jack, the PEPBOOST generates saturation and compression when used before dirt boxes. When placed at the end of an effects chain, it provides a lead level boost. It works on a 9V battery or an optional power adapter.
