Building pedals involves a lot of half builds. So you typically bread board the circuit first. If it works, you build it proper and then box it up. It’s a lot of work and kinda expensive to do to completion. So it’s good to hear it and make executive decisions on the way. If it sucks, cut your loses.

I really have not had much luck with LM386 pedals. It’s a power amp, not an op amp so it’s loud. For this circuit, somebody had the idea to drive the gain up 200 and the push that into another LM386. If your not playing it whistles and whizzes. Honestly, its unworkable in my opinion.
LM386 comes in a few flavors…maybe there is a low power one that I am missing or something. There are strengths I think??
I figured maybe if I did it on veroboard, it would get rid of that noise and parasitic oscillations. Nope. The circuitboard used to pick up AM sports radio too, but I fixed that issue. I know folks are not big fans of ceramic capacitors. I think I could have used more film ones. ( They are in the mail )
So I wish it away into the cornfield of half builds. A box of failed dreams, and successful builds that just sound aweful.
