I have a 1980 360 Ric. I have owned for 15 years. I got a pickup selector switch and replaced my broken one after I retired it playing live, just so I could store it fully funtional about 8 years ago. I brought out the guitar to record with and the middle position is the only thing working. I tried a cleaner but didn't work. Now it is playable with the neck and bridge but not complete. Is there away to chek it with a meter. If so could you give me an idea how to do it.
Thank you for your time.
