Hello stranger, this is my first PCB build (and my first forum post as well). I've got no idea why this thing isn't working; I have made sure that the switch is working and have measured all of the resistors. I get the correct voltages on R1, R5 and D100. I get my clean guitar signal when the pedal is bypassed (obviously). When I turn it on the LED turns on and I can hear a noise when toggling between Germanium/Silicon but that's it... No guitar, no fuzz, nothing. I have uploaded a few pictures of the PCB for anyone interested. Should you have any ideas or advice for me on this issue, please let me know. If anyone knows how the 4pdt pins are numbered in the schematic, feel free to share your knowledge with me as well (I'm pretty sure I've figured it out already but "pretty sure" isn't good enough for me).
