Update: I tightened every screw I could see on the body, including tuners, mounts, pick guards, tailpiece, PUPs to body, strap buttons, etc…there were four screws that mount the saddle-adjacent PUP to the body that were not capable for being tightened, they are pretty much loose and I’ll have to remove them and plug the existing holes with wood/glue to get them to tighten properly, but that’s not where the buzzing does seem to be coming from. When I play a string, I can hear some buzzing coming from inside the headstock, and perhaps from the truss rod cover area. I removed it to look inside, and there was some paint/junk material I carefully cut away to expose the end of the truss rod. I cleaned it with a small bottle brush and removed any dust, but the rattle sound continues, as does the resonator sound from my Mesa Boogie only on the “D” string.
I’m including a photo of the body and I’ve circled the four screws on the PUP that won’t tighten.
I’m going to hope that when I put new strings on it, the resonator goes away.
I’m hoping that everything is fixable…but now I’m wondering if I found maybe the reason why whomever owned it for a short amount of time got rid of it! This bass WANTS me though, I can tell. So I’m not giving up on it yet.
