Hi, I bought a new Pickguard for my P bass. Unlike a jazz bass, the pots and jack are fastened onto the Pickguard. After carefully removing them from the old Pickguard and placing them carefully in the cavity, I put the new one in place and reversed the process. Nothing.... No sound whatsoever. No hint at all that there's any current at all. I checked all the connections, etc and everything looks like it should. I should add that the bass is a Squier Vintage Modified 5 string P bass so maybe it's because the pots and wiring are cheap stuff? Any suggestions or help is much appreciated.
