Ok. I have a Dean Markley guitar that I bought when I was young and dumb. It's a great one piece guitar and all, but everytime I plug it into a nice expensive FX processor I get no sound. It works fine on amps, but no FX processors.
There is a 9V battery connected to the wiring that really confuses me. If anyone know what the problem is, let me know.
I have tried playing it with and without the battery and been unsuccesfull in solving the problem.
