I have the JC bass that has a couple of issues. 1 - output seems low, 2 - no perceivable change when switching the varitone. I have a schematic but this bass is not wired at all like the schematic. According to other threads, it's not uncommon for this bass wiring and the schematic to be quite different. My electronics troubleshooting skills are not the best so I'm hoping someone out there knows something about the wiring. If I posted a photo of my wiring, can someone check it over and see if there is any reason for the above two problems? I would really appreciate any assistance!
