My first build was the angry andy plus. I built it in a 1590BB2 because I thought more space will be better and I'll get to move some pots around and add a battery connector.
Then reality hit me hard. I did not plan my drilling so well, so goodbye battery space. Then it was hard to box, only to find out that thing would either not work or go into crazy feedback noise. After replacing the IC and having it working, I just got rid of it.
I'm not sure how I did not got discouraged by the experiment.
