That's a good check to do. You also might see that the back of the damper lifts oooo so slightly before the front. If they're absolutely flat, they may have a tendency to produce that "zing" sound on slow release of the key. Let us know how you fixed it!

You can trim that felt, and compress it, but then need to re-time the damper since it will sit just a bit lower.

Obviously it's a very nice piano, but the owner is complaining of improper damper function on several notes starting above C4, especially on shift. The hammers all shift off of the first string in Faziolis so I can see that there might be some phase shift between the strings of each unison challenging the dampers, but he's only complaining about a handful of notes in the fourth octave. The fact that the owner is formerly a synth player is likely why this effect was so noticeable to him, but I must admit the buzzy cutoff on a slow release of the key is not at all subtle. Even the dealer over the phone could hear it. So far, the trichord wedges are exerting equal pressure on the strings (plucking doesn't reveal any leaks or uneven damping) and the dampers follow when pressing on the strings. The technician who prepped the piano didn't notice a problem but who checks damper function on shift? Anyone care to take a shot at it? Tom Cole The Famous, the Infamous, the Lame - in your browser.
