JD, Thank you for the info. I've learned something today. The Pianos you mentioned are of course, European, so that explains my ignorance regarding the use of Spruce in Bridges. BTW, I meant the fumes comment as a joke. I probably have seen an American Piano with the same thing, but didn't realize it. ?????? How are you doing with the scaling program, in regard to the Impedance calculations? Best Regards, Joe Garrett, RPT, (Oregon)
