Hello, my Epiphone SG's trebble pickup volume knob has always been loose, but the other day, it kept spinning, and spinning and I didn't realize what was happening, I was playing it and then ... silence. The wires on the volume knob were broken I'm going to solder it back, but I dont know the schematics. The other volume knob (for the rhythm pickup) looks the same, but different colloured wires. Does anyone know of a site I can visit to view a good picture of a proper way to solder these wires?
