Prototype resonant high-pass filter, skiff friendly

One of my old-skool modules, now looking for a new home as it has been supplanted by a newer, flashier model.

Resonant high-pass filter which uses a multiple feedback topology - there are two controls, one for the cutoff frequency and another for resonance. This filter has been tuned so that it is capable of self-oscillation if you push it hard enough. HPFs don't get enough love, and they're a lot more useful than you might think.

4HP panel, Erthenvar jacks and Song Huei pots topped with Davies 1900h clone knobs in a fetching shade of purple. The panel itself is 4HP wide and is laser-cut from 3mm birch ply and hand coloured. If you don't like it, replace it ...

Power cable is included.
