PLL Ringmod Octave Fuzz

[Zwachi]

Hi folks!

Currently I'm gathering any info on Ring Modulators and their different advantages and disadvantages in design.
I came across Parasit Stuido's new Corruptor design which uses a 4046 PLL chip as oscillator. I already built two "Into the Unknown" PLL Fuzz and have a Schumann PLL on my solder bench.Now I wonder if I could mod the circuit for ringmod sounds and other fuzzy waveshapes.
Here's what came to my mind:
Switches for two oct up/oct down and off, momentary drone switch and time switch for the VCO. At least there's a waveshape switch which signal can be blended with the octave signal.
Anything wrong with the circuit what could cause problems?



Thanks a lot!
