BOOSTER PEDAL You can use this pedal as a buffer when using long cables, as a Boost for picking or to improve the sound of an amp. As you increase the Boost control, the sound will become richer, the volume will increase and a dynamic boost will be achieved that provides definition and clarity to your picking. From 50% it begins to saturate the amp to reach a true overdrive of the tube preamp, finally obtaining tremendous sustain with a warm fuzz. It can reach 27dB. It operates at standard negative 9V and consumes less than 100mA.
