I travel quite a bit for work. I live in the northeast. I normally keep my guitars in their cases with humidifiers. I went away for a few weeks and left my favorite guitar hanging on a stand. My house is extremely dry. A room humidifier won't work because the house it too open. Anyway, I came home realized the guitar had been left out. I looked it over, seemed ok, and then started to play it. Second (or third) dumb move. I heard the crack before I saw it. The finish on the top cracked along the seam. I am just sick about it. My repair guy said that the crack didn't hit the wood, just the finish. He said that I could refinish it, but that would change the overall sound of the instrument. At first, the crack seemed to improve as the instrument was re-humidified, however, now, as I continue to take it out and play, I think the crack is getting bigger. Not sure what to do. Any thoughts? The guitar is a Patrick James Eggle Linville. Needless to say, I will never leave home without checking the humidifiers in the cases.
