There is no particular need for high mass in the bass bridge, but it's not<BR>
particularly bothersome (or noticeable) either. Remember, mass has more<BR>
effect on the higher frequencies and springiness on the lower frequencies of<BR>
the piano's energy spectrum.<BR>

Sustain isn't bad but it does kind of have as hollow sound. Get it? But really it lacks beef. I'll probably put a solid body on it under the cap and remove the small apron so as to glue it directly to the board. This arrangement I know I prefer the sound of .</FONT><FONT COLOR="#000000" style="BACKGROUND-COLOR: #ffffff" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

I see no reason why a bass bridge body could not be made out of spruce or<BR>
maple or beech or ash or everyone's favorite--Select Hardwood--for that. I<BR>
doubt the acoustical differences would be all that noticeable. The choice of<BR>
material used in the body--either good or bad--will certainly be less than<BR>
sticking a cantilever under there.<BR>
