I'm having some trouble with a bass a got new back in April. The neck has too much relief but the truss rod appears to be as tight as it will get. If I loosen the truss rod it does what it should and adds more relief. Fender specs say .012" / 0.3mm and I can only get it to about twice that before the truss rod is too tight to turn. It's playable like this but doesn't feel great.
The shop I ordered it from says they'll fix/replace it for free if it's faulty but is probably just a seasonal thing and I'd have to pay for the work plus shipping if it turns out to just be a setup problem.
I not really sure what to do now. It seems like you should be able to get the neck straight on a newish guitar even with the changing seasons, but I can't really afford to get stuck with a big bill over nothing... Anyone got any ideas?
Quickest fix I can think of: are you willing to try lighter gauge strings? Other than that, the shop is propably right. Impossible to say before they check it and that can turn out either way.
Edit: I mean if it was mine and not that expensive, I'd propably try bending it manually and give it a good crank. Maybe first put it in a box or cabinet big enough with something to moisturize it first. But that's risky. Propably dumb too.
Edit 2: Actually moisturizing might help. I had a similiar problem with my acoustic guitar and some extensive moisturizing did help.
