Guitar wiring 101. Well…..in this case Bass Wiring 101. There are so many things wrong with this Fender P-Bass wiring. First, the electrical tape. Second, the horrible ground solder joints.Third, relying on the pickguard foil for grounding. Last, the ground wire that is supposed to connect to the bridge was not even touching the bridge at all. I replaced the pots and rewired the bass. In the end the electronics will be much more reliable and it actually sounded clearer and a bit louder. It is important that the wiring is neat and the solder joints are solid & clean. Makes a big difference!
Here is what it looks like after I rewired the electronics.
