What's going on here!?!?! Hmmm..Could be just really tempermental after a severe climate change. Middle aged K&C's ..... perhaps early menopause ?? :) In anycase.... if you cant find anything visual wrong...plate bolts, cracks, and the rest.. then you arent going to find out much unless you tear the thing apart. Tune it again in a couple weeks and see how it behaves then. What condition was the soundboard in ? Might be interesting to have a before and after aclimatizing picture. > >Then I decided two things: 1) That thar' pie-anner's got some problems; >and 2) I had better go the the store and get a bottle of wine and some >chicken to grill.
