alright so recently I purchased a Fender Modern Player Jazz V. Great sound but I've noticed the strings are digging into the top of the neck and creating grooves. From what I've heard this is a common problem with basses that have a trussrod access at or around the heel of the neck. How can I fix it so it doesn't cause more damage? it looks like its just the lower strings(B-E-A) so is it a matter of adjusting the bridge? Also what would I use to repair the damage already done? epoxy?
