Having discovered that my Gretsch no longer makes any sound electriconically, after thinking it was a switch problem as it had been working in one position, I took it all apart and with the electrics out, managed to get a sound from all three switch positions. However, after replacing the electrics into the body, no sound again!! I used braided wire as suggested originally, and have actually applied tape to that in some positions where I thought maybe wires were shorting each other out; but to no avail. Any suggestions folks?
