I have a 13 course lute that was built in New Zealand, and is now in SLC, Utah.
There's definitely a crack forming just to the right of the heart decoration at the bottom of the soundboard (toward the treble side). I've got the dampit in there which I wet every other day (this is what the maker recommended, there is a hole where the strap peg usually goes, and a dampit fits), and then two oasis case humidifers in the case. I have a hydrometer that reads around 50 all the time, or sometimes just below. The action seems to be getting a bit higher. Is it possible it's cracking from too much humidity? Is there something I can do to stop it? I'm worried about it getting worse. I just got this lute in February after waiting since 2007 to get one. I'm really kind of bummed out about this. Any help would be greatly appreciated. To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
