here is a pedal I did a while ago, a pedal pcb green ringer. Looking at my janky ass wiring I can see how far I have come in the last year. Enclosure was used for a prior project hence the jb weld filled holes. Should have painted it black like cooder. I was watching Avengers Endgame again and had the idea to redo this pedal as a tribute to Tony Stark and I give you the Tony Stark Blue Ringer. Iron Man 1 era arc reactor with blue led.

Nice! I bet if you would have painted it black inside it would have had a lower / darker octave as well... LOL...
