The Pushking 800 Fullboost was developed to achieve the dynamics and overtone behavior of an additional tube stage. The gain control corresponds to unity gain when fully counterclockwise. Two mini toggle switches enable a lo or hi cut. This allows the booster to be more focused for solos. In a linear setting, the booster gives smaller combos more liveliness and volume. The device is operated with 9 volts, although it works internally with double the voltage. The true bypass switch has an optocoupler to minimize switching noise.
