A couple years ago I made a move from Seattle to Minnesota and brought along my gypsy guitar. Despite my best attempts to keep it humidified it looks like I have finally suffered some effects from the dry winters.
My best guess is that this is due to the neck shrinking in a low humidity environment, which causes the frets to protrude out slightly and delaminate some finish from the wood causing the bubbled look around the fret. Running my fingers across the frets, it is also quite bumpy. Is this intuition correct?
Will ignoring this cause long term, severe damage to my guitar? Can this be fixed by a luthier? I'd guess that they would file down the frets around the side of the neck and reapply small amounts of finish, but I have a very basic understanding of guitar anatomy and repair.
Thanks so much!
