Vactrol Distortion with Diode Clipping & LPG

CLIPPING CAT will make your sounds meow! It’s a Vactrol-based distortion that will easily cram a lot of filth and grit into your tone. From sine waves to kick drums, this cat won’t miss a scratching post! Based on the passive and very simple WORKMATE CLIPPING CAT, this souped-up 3U module now features three main controls. GAIN determines the amount of distortion applied to your signal. LEVEL decreases the signal level that is fed into the circuit and the CAT/NO CAT switch activates or deactivates the additional diode clipping function. You can choose whether you want hard (CAT) or soft clipping (NO CAT). Depending on the diodes you solder in, the clipping behaviour and sound will change drastically. CLIPPING CAT will only blink and meow if you set the switch to “CAT” and have set a good amount of gain.

The amount of gain can also be voltage controlled using the CV GAIN input socket. Each incoming CV signal can be attenuated with the corresponding potentiometer. The overall gain range can be adjusted using a trimmer on the back of the board.

This CV functionality also allows CLIPPING CAT to be used as a low-pass gate with the smooth vactrol-based behaviour we all love. Another trimmer allows the circuit to be optimised for LPG or distortion purposes.

To simplify the exchange of diodes for soft clipping mode, there is a “diode playground” on the back of the board where you can easily exchange through hole diodes . Feel free to experiment with different types of diodes and discover novel distortion sounds. Purr!
