[pianotech] Damper Issue???

[John Formsma]

With all our fancy smartphones, could you record that noise and post it
here?  (Not sure if the list will accept mp3 or WAV files, though.)

Did you hold the damper head with one hand while striking the key "with
force"? That gets the damper out of the equation, and you can move it enough
so that it won't be possible for the wire to contact the string. This way
you can determine if the sound is from the damper wire or something else.

This is the first thing that comes to mind, without being there and hearing
exactly what you're hearing.  I suppose it could be possible that a paper
clip is somewhere on the soundboard. Those rubber-coated soundboard steels
that Pianotek sells would be handy if that's the case.
