Hi Mark and all.

I run into the same third bridge problem on my 1891 Steinway A.  It =
sounds awful, while the rest sounds great.  Pitty to hear that changing =
for bichords instead of trichords didn't help much for the sound.  I =
feel I could possibly be ready to follow Terry F to the shop of Del F =
and ask for redesinging.
Does anyone know what the hell those splendid engineers of Steinway had =
in mind when desinging that third bridge ?

Regards,

St=E9phane Collin.

  I did an old S&S A1 over with all bichords on the third bridge. It =
still had that "third bridge" tenor sound, but at least the top 7 =
bichords were 33% easier to tune! Plus they damped better.

       To all esteemed scaleheads,

    I just received a AA for a complete rewhatevering & I'm very =
unimpressed by the bass tenor break. This one is 1919 with 2 bichords & =
7 trichords. With all of our discussions about third bridges & such I'm =
drawing the conclusion that this on is ill devised. Tonally it abysmal =
to the ear. I learned from a friend who is doing another dated 1931 that =
this vintage has all 9 transition notes in bichords. He & I have yet to =
hear it as it's not done.

    I'm considering either switching to 9 bichords with the old bridge =
but the string lengths seem dreadfully short. Does any one have the =
string tension logged for this model. My guess is it would be =
instructive.=20

    The other option is to do away with most of it and use the small =
piece that juts out toward the spine.

    Any body out there played with this model?
    My 1950s AA has one long bridge with 5 bichords. It could have used =
6 as note27 is wiry sounding. Kind of honky& low tensionish. I'll know =
more when I run the scale.

   It's obviously a design that has been transitional.

     Any thoughts, Ideas?
