I'll skip to the TL;DR:
I populated a Moodring board and it doesn't work like it should. There is a lot of weird feedback (at certain high frequencies, not full audio feedback), so it's more or less unusable beyond very minimal effect settings.
I'm maxed out time-wise between dayjob work, Function f(x) work, and being a new dad.
So if somebody has the time to troubleshoot this almost-working board, I would be very appreciative. I can compensate your time with cash, parts, PCBs, or something else you might need or want (will to "moose stuff" if necessary :) )
Thanks!
I'll do it.
Much appreciated, Jon. I will send you a PM forthwith.
