This is an active variable HPF that offers you the ability to select a cut-off frequency anywhere inside the range 200Hz-20Hz by using the respective knob. The filter’s curve is quite steep offering a 12dB/octave attenuation.
Additionally, by using the 2nd knob you can change the output impedance of the circuit and choose a value in the range: 0ohm-220kohm.
This feature can be useful in some cases where a pedal with low input impedance follows the filter (e.g. a germanium fuzz, vintage effects, etc) and might sound much better when paired with an output impedance that resembles the impedance of an instrument’s passive pickups (typically around 10k-20kohm) or even higher.
It’s the ideal device if you are looking for something to help you “clean up” the low end of your signal. It will work fine with active or passive instruments, as well as with other devices such as pedals, preamps, or even in FX loops.
The HPF circuit can be completely bypassed using the footswitch (true bypass).
