Re: do you carry an acoustic Guitar?
Google "carbon fiber acoustic guitar" and see what you get.
I don't know specifically how good cf guitars are, but cf cellos are very good, can be played under water and take a beating with no discernable damage. Last weekend I watched a student play his cf cello for a professional ensemble and they did not realize that he was playing on a "plastic" instrument, even though one of them was on a cf cello. Most of the cf cellos sound like cellos, whereas the electric ones sound like synthesizer music.
As to price, cf guitars at <$2k are a really good deal. Cf cellos start at $7k, but then everything cello is more expensive, like $200 for one string!
ps. high humidity will eventualy take a toll on any wood instrument. The humidity will dampen the sound and the instrument will loose some of its brilliance.
