I have a Bastion PCB I never got around to building. I looked at the build docs and there is a 8.2k/100nf 194hz LPF sandwiched between the clipping section and EQ. I'm convinced that's a mistake and it should be a 10nf capacitor to make it more like 1.9khz, but like I said I haven't built it yet. That's gotta make the overall sound of the pedal bassy/warm/dark and in turn the EQ section frequencies act weird.
edit: looked up some gutshots and the two that I found definitely had 100nf caps and 8.2k resistors, so what the hell do I know lol
