The Mercurial Boost is a pedal that is inspired by the Catalinbread Varioboost. It features three controls: Frequency, Boost/Cut, and Gain. The Frequency control allows you to adjust the center frequency of the pedal, ranging from 70Hz to 1.4kHz. The Boost/Cut control determines the amount of boost or cut applied to the selected frequencies. Lastly, the Gain control adjusts the overall output signal level of the pedal.
