For me, it's still a matter of the wood's stiffness to weight ratio and so far the best is Sitka spruce. As far as processing is concerned, I'm not sure there are any real secrets. Our wood is kiln dried to about 7% to 8% before we begin our own conditioning. We take it down to 6.0% to 6.5%. All of our processing is done at this EMC. But then, our ribs are dimensioned and crowned accordingly. We do look for even color for a pleasing appearance and uniform grain for a consistent stiffness and weight. Competitive pressures dictate that we reject certain cosmetic flaws that I doubt affect the tone performance of the soundboard in any way. --ddf > > Was Dolge then laughing all the way to the bank with the > > revenues from his sb's?

A close reading of Piano Tone Building shows that the nature of the functioning soundboard was poorly understood and much importance was placed on factors that by now we should know better than to continue promoting and believing. --ddf Delwin D Fandrich
