Is it thuddy all the way down or just in the low bass?  Who made the =
strings
and did the rescaling of the bass?  When you rescaled the bass what kind =
of
core wire dimension did you end up with in the monos and how did the
dimensions compare overall with the original?  The original Steinway =
core
dimensions on those are quite thick (.063 at A0 often).  On pianos that =
I've
had rescaled I've noticed that the core wires ended up somewhat thinner =
and
that double wraps were added in the low bass.  These rescalings have =
always
improved the tone at the lower part of the piano. =20

List,

=20

We just finished a restringing/slight redesign of a 1963 Steinway =
upright.=20

=20

1.       We ground down the "bump" and lowered the pressure bar =
slightly.
This made tuning a LOT better. Easier and more stable.=20

2.       We shortened the apron on the bass bridge (cantilever) to give =
85mm
(backscale) on the lowest bass note. It was 40mm.=20

3.       It now has Pure Sound stainless wire. This made the biggest
difference. Richer, more stable.=20

4.       Added a small tenor bridge. I'm not sure if this made much of a
difference, but the break does seem to be smoother and the bichords seem =
to
have a slightly stronger fundamental.=20

=20

A side by side listen with the same model showed vast improvements in =
the
plain wire sections. I think this was mainly due to the stainless wire.
Also, it tunes like a dream now! Removing the bump was easy and well =
worth
it.=20

=20

Although the piano is improved, in some ways greatly, I still don't like =
the
bass. It's better than the old design but still a bit "thumpy". Any
feedback??

=20

I attached a "before" picture and a close up of the bridge changes. The
"bump" area looks like the new 1098s so I didn't take a picture of that.

=20

I highly recommend the "bump" removal and the Pure Sound wire. Jury's =
still
out on the other changes.
