I have a truss rod adjusment question for you guys that I hope you can help me with. I have an 02 American strat that had too much relif in the neck. I tightened the rod at the headstock by about 1/16 turn and I heard a slight creak or pop at the headstock. Needless to say I stopped there. How much ressistance should I be feeling? If someone could answer my question it would be greatly appreciated.
