Im sorry if i alreay posted this before, or if its in the wrong place, but i got no response before. The neck on my OLP Stingray is warped a little, causeing the strings to rattle on the lower frets. its warping twards the strings near the middle. I know i have to adjust the truss rod one way or another, but im not sure how much or which way. The thing to adjust it is at the end of the neck on the body. Can anyone give me some advice?
