for starters, I would trim those leads coming through your PCB so they cannot touch any of those wires soldered in to the board. and check to see if that gets you any different sounds from your board. please post a photo of the other side of the PCB board as well. in order to troubleshoot a board that does not work you need to be methodical checking the different parts of the board to see if the power gets to where it needs to be using a DMM, make sure the ground connections are intact (DMM), making sure things that are supposed to be connected are actually connected (DMM), and using an audio probe to see where the sounds stop getting to the right place. The good news is that most of the time you find and fix the issue before you go through all of those steps. It is great to build an effect and have it work right away, but thinking about what might be wrong and how to test the different parts of the project is rewarding when you find the problem and fix it.
