Check out CA Guitars. (stands for "Composite Acoustic.") They're making guitars entirely out of synthetics, and the buzz is that the tone quality, while not up to that of the very top-end Martins or more expensive guitars from small shops, is fully comparable to, say, a middle-line Martin. And you can throw one in your car trunk without even bothering to put it in the case, or leave it outdoors with the rain falling on it when you camp out, or take it to the beach and let your kid use it for a shovel in the sand...no problem. Some very well-respected country and Bluegrass musicians are using them for touring instruments, because they get as good sound as they really need in a touring situation, with no worries.

If good-but-not-great instruments can be made from synthetics, that means we can save the dwindling supply of tonewoods for great ones, nicht var?
