Cat Girl Synth – CGS49 Dual WASP Filter

A unique “Tribute” filter to the ’70s WASP Synthesizer, the CGS49 Dual WASP (CMOS) Filter doesn’t fail to amaze!

While the CGS49 combines two separate filters this version permits control voltages to be shared between them.  Voltage input through the SPREAD CV input are passed through the potentiometer and then simultaneously to the +CV & -CV inputs of filters 1 and 2.  In addition, because the each filter’s CV input are linked at the SPREAD potentiometer a certain amount of bleed-through can be achieved by simply adjusting the SPREAD potentiometer without and SPREAD CV input.

Our latest version of the CGS49 includes a new SERIES / PARALLEL normalizing switch.  This will allow the audio signal to be sent to either filters 1 & 2 simultaneously or sent first through filter 1 and then through filter 2 without any additional cables or splitters.

The CGS49 features Low Pass, Band Pass, High Pass and Notch frequency output filters.

Each channel’s Inputs include Signal as well as + or – CV.

The CGS49 Dual Wasp Filter comes in a 2U width with 1″ (25.4mm) knobs controlling 8 potentiometers (4 per filter);

  • Frequency Cutoff
  • Resonance
  • Distortion
  • + Control Voltage

A 30mm knob is used for a potentiometer controlling spread of CV between filters.

The module operates at +/- 15V and comes with a MOTM style power connector.  Included is an MOTM to power connector adapter.
