I've always thought that Yamaha and Steinway keybeds were built with expansion joints and that there were, in essence, slots in the bed. I added Dampp-chaser rods under them because of that, thinking that here in LA this would help the action, pinblock, etc. But I recently cut into a C3 for PianoDisc installation, (maybe a 4 year old piano) and found that the top and bottom veneers were spruce, but the "slots" were fake and the keybed was essentially laminated mahogany, etc., solid, with a moisture barrier on the top and bottom. Does anyone know when they started this design or have any more info on this?
