[pianotech] High Pitched Zing in Acrosonic

[John Ross]

Is it on the attack or decay of the note?
If on decay I would suspect dampers being hard, and zinging as they return to damp the strings.

An attempt has been made to tighten all screws and check anything metal.  It aomost sounds like a "dangling" caster, but the piano is on plush carpet.  The piano has been moved away from the wall to check for possible vibration in nearby picture.  Will try bushing cloth on the upper duplex tomorrow.  Also, the high treble action bracket is loose on the keybed adjustment screw and will be tightened.
