Was feeling super confident with this one..alas no sound.
After I saw that I had forgotten to install the OpAmp I figured I had it solved.
Not so...no sound.
I accidentally substituted an A100k for the A500k because I soldered before I realized it was on the wrong side. I know that’s not ideal but I don’t think it’s my problem. I’ve got lights and pass through but no effect.
If you see anything obvious please let me know. May have some time tomorrow to troubleshoot.
