Thonk Humpback Multimode Voltage-Controlled Filter Now Available

Thonk has announced availability of the Humpback multimode voltage controlled filter, a 2-pole, CA3080-based implementation of the classic state variable architecture.

The controls of the filter are:

  • Filter cutoff – a hardwired DC voltage frequency control
  • CV inputs – two frequency CV inputs are included on the panel and controlled by attenuators.
  • Outputs – lowpass, bandpass, highpass and notch are available simultaneously
  • Signal input – one signal input is available on the panel
  • Resonance-resonance control is included and is hot-rodded to allow self-oscillation. In self oscillation the filter will produce a sine wave output.
