[pianotech] Bridge pin locations help (image oops)

[David Love]

Do you mean because of the non uniform speaking lengths?  Did the pitchlock
help?  I'd be curious next time you are there if you might try attaching a
vise-grips to one of the bridge pins in such a way that it doesn't make any
noise (rear bridge pin is ok) and see if the false beats still occur.

List,

I decided I would share a situation I have had
  to live with for several years.

I regularly tune a 2001 Steinway Concert Grand that has
  a definite issue with the location of the bridge pins.
    (see image)

Throughout this piano there are varying degrees of
   misplacement of the bridge pins, however the one I focused on
  is by far the worst offender and produces false beats beyond belief,
  hence I added the PitchLock String Coupler to reduce the false beats
existent.
         (  http://www.pitchlock.com  )

Does anyone have a surefire method to correct this issue 
  without a tear down?    (larger pic available if needed)

Sincerely,
