High overtone

[Paul Chick (Earthlink)]

Yes. Both strings produce the overtone with the same intensity.  Yes.  It
stops immediately when the damper comes to rest on the strings.  After
looking at this piano and its quirky high pitched overtone, I've listened
carefully to about 5 other grands of this size from new to 40+ years old.
The high overtone can be heard in all of them, but it is subtle and cannot
be made to "sing out" as it does on the new Kawai RX-2

Do both strings of the unison produce the overtone, and does the overtone
stop when the key is released?

A customer has a new Kawai RX-2 with a very high and loud overtone on F2.
It rings over the F2 whenever the note is sustained as a single note, note
of a chord, when the sustain pedal is pressed. Recent tuning had no affect.
I squared the hammer to the bicord, checked bridge contact, hitch pins,
centers, etc.  The duplex is very lively.  I couldn't find the offending
partial in the duplex, but I'm not ruling that out.  Has anyone come across
this in the RX-2?  Don Manino.are you out there?
