I seem to be having some issues with the Seabed Delay that I just built. This is only the second pedal that I've attempted building, with the first being a BYOC kit, so I am very new and inexperienced with pretty much everything. The pedal only works bypassed, and has no signal through it when turned on. By playing around with the pots I can get some sort of oscillating delay, but nothing with the actual guitar signal. The LED also only worked for a few seconds before burning out, so I might have done something wrong with that as well. All of the components are the correct parts, with the exception of a 15nF capacitor that I used a 10nF in replacement. Being new to this, I really have no idea how to troubleshoot, or what I should even be googling to try and figure this out myself. I also have the components to build a few more pedals, so I'd like to try and avoid repeating any mistakes that I made with this one. Any tips are much appreciated, and thank you in advance!
