Good day sirs. I have an LP custom but its arm is curved upward, meaning, if you press the strings to the fret at both ends, you can see a 2 milimeter gap between the string and the fretwire in the middle section of the arm. How can I solve this? Thanks
you're talking about the neck. you can adjust the truss rod. if you dont know how, google it or take it to a luthier or tech.
tighten or loosen? thanks dude
tighten of course.
you want a small gap... 0.4mm
