The Pro-Filter is a pedal that is inspired by the Anderton Super Tone Control. It features several controls that allow you to shape your sound. The Volume control adjusts the output volume of the pedal. The Frequency control sets the cutoff frequency of the state-variable filter. The High Pass control adjusts the output level of the High Pass filter, while the Band Pass control does the same for the Band Pass filter. Similarly, the Low Pass control adjusts the output level of the Low Pass filter. The Resonance control allows you to adjust the resonance of the filter. Lastly, there is a toggle switch that lets you select between Hi or Lo resonance peak.
