I'm not very handy, but I have several basses which are vintage Fender replicas and require loosening the neck to get at the truss rod screw. I've done this today for the first time in my life, and applied a quarter turn of tightening, which has helped. I'm quite pleased with myself.
I would do another quarter turn, but when I tried, the truss rod wouldn't go any tighter and I didn't want to force it (this is all with no string tension on the neck). On balance, I think the action has improved and I'm happy. I could just live with this action, but I'm wondering whether being at the end of the truss rod's adjustment is (a) a bad idea for some reason or (b) a sign of future troubles stored up.
If I *did* decide I wanted another quarter turn, what's the best way for a DIY klutz like me to proceed?
