Tuning problems under capo bar

[Joe And Penny Goss]

Hi Michael,
I believe the string going sharp may be caused by the over flexing of the
tuning pin in a downward direction. When the string is struck the pin
returns to its memory position which draws the string sharp.
BTW
No one responded to my desperate cry for help with Pearl River uprights O:(
Well here is what I found.
The previous techs ( not PTG ) answer was to
address the slugishness by graphiting the ballance rail bushings.
Well he did no harm but did not fix the problen
I will tell you it took 2 minutes to remedy each piano.
Now take a guess <G>
