[CAUT] Fiberboard

[Douglas Wood]

I have it from a high-level source at Steinway that the back side of  
this (closest to the agraffe) needs to be high enough that you cannot  
get your fingernail between the strings and the cloth. It does seem  
to me that those pianos that do not meet this criterion tend to have  
more agraffe noise in an unpleasant way. This may be why they have 3  
thicknesses of fiberboard on hand, though that's my speculation.
