When I mute either string it still happens. I moved the damper head up and down, left and right and every which way and checked damper timing - nothing helped. It appeared to fit nice and neat into the gap of the bichord. It was seated firmly against the bridge and bridge pins. The strings are aligned at the v-bar. <BR><BR>Is it possible I just didn't get the damper to seat just perfectly? After I left I thought of this possibility: maybe the damper felt is too tough. Perhaps replacing it with fresh? or a softer kind? The other notes just above rang just a little as well, but only half as bad. <BR><BR>Or is it just the piano? Can nothing be done?<BR><BR>-Noah Haverkamp Frere<BR></BLOCKQUOTE><BR></BLOCKQUOTE></BODY></HTML>
