Help with soda meiser

Can someone tell me what's technically happeningto the circuit when the chaos switch is flicked.

I can see it seems to remove/include a 0.1uf capacitor across the C and B of Q1, but why would that have the effect it dose of all the glitch sounds?

  A cap[ between collector/base [on a gain stage...output from collector = inverted signal output], is a LP filter.
   Only freq's above X can pass through the capacitor with low enough impedance to be 'heard', because the active stage is inverting, the HF's that Are allowed through, from C to B, cancel.

Awww......Was wondering about this pedal too (as you been banging on about it Comp!)....so the switch is just a Low-Pass filter (or due to the inverting is it a HP filter?)  

Teach me more please petemoore

You should know this Brook

Thank you petemoore !

I think it is a big LPF... probably to obtain a graveyard or earthquake kind of sound, killing nearly all the treble 

Thanks for sharing this interesting schematic

A+!

Dose the excessive size of the cap also increase the signals phasing you get with LPF, giving you that out of time of randomness to the signal?

**** you!
