Based on the Roland System 700 state variable filter module. Lowpass, bandpass and highpass outputs. 2 audio inputs, 2 cv inputs
A big part of the sound of the State 700 is the way in which resonance is reduced as the audio inputs are driven harder. It won’t self oscillate with a hot audio input, throttle back a little and you’ll get squelchy ear bleeding resonances!
This is a complete kit EXCEPT OF the knobs. Everyone has own preferences and that's why we didn't include them. You can get suitable knobs here. The components are packed, presorted and labelled according to the BOM where necessary, so you can start soldering immediately.

We carefully selected and assorted the parts of the Frequency Central kits ourselves and also put special emphasis on quality - audio grade electrolytics in the audio signal path, resistors form Yageo and Royalohm, Alpha pots, quality jacks, precision sockets and switches, etc.
