so i'm not sure if this is a dumb question but here goes... about once or twice a year i notice a little too much relief in the neck of my P bass. it gets uncomfortable to play and i have to tighten the truss rod just a little bit. i almost never need to loosen it, which made me think: if i'm mostly tightening it year after year won't there come a time when it's as tight as it can get? will it be screwed at that point? literally and figuratively i've never heard of anyone maxing out a trussrod in the way that i described, but i would appreciate any insight you guys could offer!
