Dear List, A technical question. A fellow technician recently had a board replaced in a 9' Knabe. The original board had a gap around the perimeter of the board in places up to 1/4". Should a board be glued right up against the case and would this have a "coupling" effect on the sound, or isn't this important? I've heard one reason the far-east pianos have a characteristic sound is the unavailability of certain hardwoods in case parts, etc. This suggests to me that the case resonates to a certain degree contributing to the over-all sound. Hope this generates some thoughts. Regards, Bob Sadowski RPT Erie,PA.
