The current Steinway Technical Reference Manual says: "It should be noted the key dip may vary within the suggested range of .390 inches and .420 inches for any Steinway grand piano. However, extremely shallow key dip will result in lost power. Extremely deep key dip will result in reduced action performance with the sharps "burying" below the naturals." dp David M.

The keydip for the B and D is 390mm, while the keydip for the S, M, and L is 420 mm. The info I have is: S, M, L, B @ 9.5 mm C, D @ 10 mm -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
