My name is Nick, in Crete, Greece, and my guitar cracked while playing ~10 days ago.
Guitar is a Takamine EC132S, circa 1984-5. Laminated rosewood back and sides, solid cedar top. It's been in its case for years and I started playing it again few months ago. It really is a beautiful guitar....
Have not left guitar in cars or excessive heat, but I've ran it through some quick temp/rh cycles lately... house, pub back yard, pub inside etc....
all the jpegs are of the guitar

Have binding separation, top separating from side s etc.
No sinking in top or back, and no fret protrusion....
Have put a sandwich bag/sponge in the sound hole, one in the neck for about 1 week now, but I dont see any progress closing up the gap at the lower bout. Maybe I need to do the "Hesh" bag treatment?
There is also a small crack at the waist that you can see in one of the photos,2nd one I think..
Anyway, I've built one guitar years ago, per Sloane, and I''ve got some parts waiting to become an archtop.
My environment year round is pretty humid, so I' kinda stumped as to what happenned. All I can imagine is the Sahara based dry winds that we have around the time this happenned.
Annual average humidity here ranges between 40- 65 year round....
Anyway, help please, and again, hello to all, I've learned alot from the frets.com site
Please, dont recommend "just take it to a luthier" as there is not much choice at the time
Right, Chad, that's the way I'd go, although I bet you could get by just fine without trying to clean out old glue. We often reglue these without much fuss.
While you're at it, get a mirror and look inside for any broken bits of kerfed lining or loose braces. This guitar looks to me like one that received some kind of blow, possibly while it was in the case, that jarred the glue joints loose in the area. That could explain the crack in the side as well.
This may be obvious to you, but if there is still tension on the strings that is causing the distortion in the sides. With the strings off, pushing the distended lower bout in will probably make the waist area come out to meet the top edge. You should not have to push the caved in area at all, or only with your hand inside the box until you get some clamp pressure on it.
