<DIV> Here are a few pictures of the S.S. O & S.S.long =
A
design. In the O picture it's more instructive to see the bridge layout over=
the
actual rib structure. You can see that the angle of the rib to the board gra=
in
getting steeper & the ribs fanning to stay paralell with the bridge. It'=
s
plain to see just how much chorter & stiffer the longest ribs were &=
now
are.</DIV>
<DIV> Ron N. & O your comments about the tone getting stronger in =
the
second half of the tone envelope are right on. The bridge has also been move=
d
back at the top treble so that the note 88 could get a 50 mm string le=
ngth
increasing tension & power. This is sop on all redo. ON the A I ev=
en
ground the plate. The original string length on the A was shockingly sh=
ort
at about 46mm & was changed to 54mm at 88</DIV>
