Mike Swendsen RPT > ----------------------------------------- Mike, There are several materials available today that would probably make good piano soundboards. Take a look at the patent files. I've worked with only a couple of them, and those only enough to probably be dangerous. That is to say, I'm not ready to give up on Sitka spruce quite yet. There are a number of problems facing the brave soul who first tries to market a piano with a composite -- or whatever -- soundboard. Most of those problems will have to do with convincing the technical community that they will really work. No matter that this board may appear in the best sounding piano the world has ever seen.
