I'm fairly certain the truss rod on one of my basses is completely useless. I've tried adjusting it (as well as the saddles etc.) to eliminate a rattling problem which keeps mysteriously appearing and dissappearing. I've been reading around about this for hours but I can't figure out how to remove the hex nut from the truss rod. Before I start trying to pry it out, I wanted to be clear about some stuff. Despite the ever-so popular "righty tighty lefty lucy" thing, the hex nut becomes difficult to turn after I have gone counterclockwise so far. So shoud I have it more or less in the middle, where it seems most loose at least in the sense that it's easy to get the nut to turn before attempting to pry away at it?
