How to build an effects pedal for boosting and cutting tones.
Shape your sound with the Tone Attack. 12 o’clock settings give an approximate unity gain with the pedal.
Rotate the treble or bass knob counterclockwise to cut the corresponding frequencies. Rotate these same
knobs clockwise to boost the frequency bands. The Master Boost knob can be used to attenuate your signal
or push your tone to screaming loud volumes.
