The filter is switchable between Lowpass and Hi Pass modes, and features an updated diode gain stage in the resonance section. This circuit was adapted by Sagitronics, who does excellent work.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin: 0px; padding: 0px 0px 1em; border: 0px; outline: 0px;  vertical-align: baseline; background- line-height: 2.3em;    letter-spacing: 1px;\"\u003e\u003cspan\u003eThe VCF will overdrive and distort in both the HP and LP modes, and the resonance can self-oscillation. As with the MS 20 Filter, the Low Pass slope is 12dB\/octave and the High Pass slope is 6dB\/octave. The CV input is an attenuverter, allowing for dynamic control-voltage of the cutoff.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin: 0px; padding: 0px 0px 1em; border: 0px; outline: 0px;  vertical-align: baseline; background- line-height: 2.3em;    letter-spacing: 1px;\"\u003e\u003cspan\u003eAll jacks, knobs, and other components are soldered directly to the PCB.
