Further information from nonlinearcircuits:

This is the 1st prototype of this module, though it only needs a few tweaks to get the gains of each channel more equal and some minor changes to the panel. 

Basically it splits the input signals into 4 frequency bands, these go into fuzz circuits and vactrol based VCAs, then summed to the output or use the individual channel outputs. You can blend the clean/distorted signal and vary the fuzz characteristics.

Further information from the build guide:

This module is made up of smaller circuits based on the following; Buchla 194 fixed bandpass filter, four Shin-ei SY2 Fuzz circuits, 4 Korg 3200 vactrol VCAs, an input buffer and an output summing sub-circuit. As the block diagram shows, the input signal(s) are split into frequency bands. Each band is then sent to the fuzz/distortion circuit and outputs to a VCA via a blend pot which mixes the distorted signal with the original clean signal. Each of the four vactrol based VCAs can be individually controlled by CV and the signal for each channel is available on the panel. The final stage sums the 4 signals and sends this to the two panel jacks.

Interesting results can be obtained by controlling the VCAs with different CVs, many new sounds and harmonics can be heard as the different frequency bands are brought in & out of the mix. It is also interesting to feed one of the channel outputs back into the spare input jack.
