Hey! Sorry for asking for help so frequently! I appreciate you all.
I built this Pyrocumulus (Thorpy Fallout Cloud) for a friend and I'm not confident about the way the sustain knob works. It definitely increases gain but most of what is happening toward the end of the sweep is it's adding a fair amount of lows. Kind of sounds a tiny bit like a clean guitar and muff at the same time? Could just be the tonal changes tricking my ear. This could be as designed or I messed up somewhere. I've reflowed every joint and added some solder to a few but it didn't make a difference. I've also cleaned off the back of the board with IPA and a toothbrush.
I took a photo in case someone with fresh eyes can spot a wrong resistor or cap but I took my time as I built it. All other controls work as expected.
Oh and here is the build doc link : https://docs.pedalpcb.com/project/Pyrocumulus-PedalPCB.pdf
If someone else has built this one and can verify the sustain knob adds low end as you turn it up - then that's probably all it is. Doesn't sound quite like the demos I heard though. Thanks!
