Hi Richard. I don't mean to burst your bubble. You have good =

not aware that her piano is imperfect. Depending on what is ultimately =
the cause of the falseness, the potential for a warranty claim is always =
a possibility. So, being that the customer is not looking for a solution =
at this time, and I am not looking for a mistake to make, I wish to =
simply understand as much as possible, and not tap at this point.  :-)

Reseating the pins? I did not push/tap the pins. I did however seat =
thestrings in every gently way I could think of.
Have you noticed that Ron has not provided input on my recent post =
regardinghow many hours one would charge a client to recap a bass bridge =
(I didrequest that no bionic bridge dudes need reply!)?  ;-)

  Perhaps he was in for a bionic check up .... or too busy with those =
two preverted posts... you know the ones... "zipping up the fly in =
public" and " sun bleached tail". grin....

Terry I have noticed the same thing on the Steinway grands, and have =

So what happened in the lower half of this section? Why did jus!
t
touching
(super-duper lightly only) the forward bridge pins cause the strings to
mute
out? On the Boston that I posted on recently, as well as many other
pianos,
you hear a false beat and when you press gently on loose bridge pin,
false
beat is eliminated AND tone remains clear
Don't worry about the muting effect... it wont happen when you CA =
orEpoxy the Bridge pins. As far as lessening of the falseness, =
youprobably achieved a very temporary solution by re-seating the pins. =
Ilike Ron N's position on this seating business... makes a lot of sense.
I'm really trying to understand the causes of so much garbage sounds
that
emanate from the high treble of pianos (er, a, well thinking of some
other
pianos, I guess anywhere on the scale!). Any thoughts on this situation?
You and just about everyone else. Its fascinating for sure. Lots =
ofsources of diverse types of noise and falseness. As far as the =
mutingeffect you observed... I think .... and only think... (as I am but =
anegg in these matters) that the Steinway bridge and bridge =
pinconfiguration is like highly sensitive to changes in mass. Clamp a =
smallvise grips onto a bridge pin on a Steinway and the string goes =
deadsounding... but on many other pianos there is only a small =

the answer isan interesting one.
