Seating/false beats

[Ron Nossaman]

Hi John,

How could you tell the strings were up the pins? Was there a visible gap? That would sure scare me!  I'd check the soundboard crown and bearing. It sounds to me like the board has gone concave and the resulting negative bearing is floating the strings up
off the bridge. The clicking sound you reported should be accompanied by a nasty distortion in the attack, followed by a weak sound and short sustain. If this is the case, the board is shot and it won't much matter how tight the pins are. When you get bac
k to the piano, please post what else you find, I'm curious.

Thanks,
Ron Nossaman
