I have a Burns/Baldwin Bison guitar that has recently been experiencing intermittent issues. After conducting tests with my technician, we concluded that the selector switches need to be replaced. We have already attempted cleaning the switches with contact cleaner, but the problem persists. I am attaching 2 photos of the guitar including the serial number. Could someone kindly provide information on where I can find reproduced replacement parts, such as the switches? I appreciate it if you could help.
