Alright, thanks. I can't find any large soldering faults in the power section. All components should be in the right place. The voltage regulator datasheet says its minimum output is 4.6V (if I'm interpreting this correctly https://www.st.com/resource/en/datasheet/l78l.pdf). Could it just be an...

Thanks! This is my first time debugging a non-functional pedal. What do you mean by 'check your values'? Check what against what? I meant pin 3, the transistor output that goes into the belton brick, is 4.6V. Is the transistor receiving too low a voltage to begin with? How do I know what the...

Hi! I've been attempting to build a gravitation reverb. I've been running into several problems (my mistake of course) but am stumped on this issue. The belton brick did output a delayed/reverbed signal before, but now mostly makes high pitched noises. It is supplied around 4.6V at pin 1. The...
