Both my p and jazz are having issues from the 3rd fret up to the nut. I guess it's possibly a weather issue, not sure. They were fine but we've gone through a few weeks of warmer and more humid to cold and dry. The jazz is the worst, it totally bottoms out and I have a hard time fretting a note unless I smash the string down. Do I need to adjust the truss rod or should I be looking more to raising string height or both?
