I just built my first pedal. I spent a bunch of time gathering parts and going over them, soldered everything well (based on the diagrams, which didn't seem to match (Pythagoras V2), but I thought I worked it out with the PCB printing), but when I plugged it in it sounds like the incoming signal is breaking up terribly. I can mitigate it a little by turning the guitar's volume way down to the point that I can barely hear it, but the crackling is gone. I can hear the effect doing what it's supposed to behind the crackling. Any ideas? I tried to post a pic but I'm on my phone and it was too large. I'll try to add some later. I'm new to pedal building. Thanks!
