SVF-1 - state variable filter

The new SVF-1 from Tenderfoot Electronics is a great sounding state variable filter with voltage controlled cutoff and resonance. The SVF-1 self-oscillates when the resonance is turned up and has a 1V/octave input for use as a sine wave VCO. The resonance circuit includes a Q control, a drive control, and a button to press if you're feeling less polite and really want to push the resonance beyond its limit and get it sounding dirty! The Q control is also controllable via a CV input jack. All outputs are available simultaneously:Low PassBand PassHigh PassNotch   A tonne of versatility from a filter in 8HP. 53 mA +12V 53 mA -12V 0 mA 5V 21 mm deep Click here to take a look at the manual!
