But I also suspect that the relatively "lively" environment of the vibrating bridge ( as opposed to the normal agraffe home -- a plate) contributes to all sorts of uneven wear on the inner surfaces. Perhaps these could be reamed, but a belly job with a conventional bridge is all that I've heard truly fixes the glitch. (And Sohmer, a fine American make, and the last to be owned by its founding family, made a truly unfortunate boo-boo on this one!) Thumpe P.S. I have one of these in my "route": owned by a hospital CEO here, with the same trashy overtones. But it also had a very bad squeaky pedal problem.

Living in New England, I am in a harsh environment for pianos with dry winters and humid summers, so perhaps I see more deterioration than you do, in your more benign environment.  Will Truitt <o:p></o:p></td></tr></table><o:p> </o:p></div></div></div></div></body></html>
