I've built my Chaos Machine and just got it working after a minor build issue, it's a great pedal but reduces lower frequencies of the dry signal and I'd like to use it on bass... looking at the schematic I am thinking that IC2.2 along with C4, R7 and R29 are making an active high-pass filter with a cutoff frequency around 72Hz and if I double the value of R29 that will take cutoff down to around 36Hz. Only issue is it's also acting as high pass for the two resonant filters so I guess I'd have to be careful of extreme filter settings... has anyone else modded this for use with bass?
[Edit] Thinking again, maybe I could get the same result by changing C4 which would only affect the dry path... 220nf looks like a good value.
