This isn't about a tele, so mods, please move if I'm posting in the wrong place. This is about a Gibson style truss rod. The guitar has a lot of relief. It's a one way rod. I tightened and tightened till I had the rod coming out the top end of the nut. Adjustment felt stiff but not super hard. I saw a Stewmac video that discussed this issue and did what they did, I just backed the nut out and was able to tap the rod back into the neck about a quarter of an inch or less. Retightened and it looks like the rod is creeping out again. What's going on here? I'm assuming it's loose inside the neck at the other end. Do I just put an extra washer for the adjustment nut and keep tightening till it really grips like in the Stew mac video? Or do I need some other fix?
