A little on how it works:

Of note is that the filter core is running between 0V and -5V, allowing a simple exponential converter to be used to give an appropriate response to the control voltage. The distortion channel straight signal are mixed via a seque circuit (reverse panner). The final stage is just a regular, inverting amplifier, but with a voltage divider in the feedback loop to avoid the need for an excessively high value resistor to achieve the required gain.

Great Filter - Tricky BuildReview by Flareless
The CGS49 pairs two Wasp filters in a single module. Even better is the fact that the filters can interact together. The build is a bit difficult and definitely not for beginners. Because there are various options for building this module it was necessary to search the Net for specific details.

I created a build document of my own based on the info I found. You can check it out here;

This filter is definitely a must-have for those searching for unique sounding modules! (Posted on 12/21/2016)
