Steinway Sostenuto

[Andrew and Rebeca Anderson]

John,
I had a similar problem on this larger Kimball.  On the Kimball it 
was inadequate pedal travel.  The blade did not drop far enough to 
allow the damper tabs to drop under after using the damper 
pedal.  Cue is some dampers don't seat well or "stick".

Presumably the damper timing is correct.
