<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top" style="font: inherit;"><div>Will,<br /> I don't doubt that the wood may be a factor. 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!)<br /><br />Thumpe<br /><br />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. Have you encountered that in yours?</div></td></tr></table> <div id="_origMsg_">

FYI<BR><BR>I have a couple of these in my service presently here in New Hampshire, and<BR>have had others in the past. <BR><BR>These bridges probably sounded pretty good in 1925 when they were new, but<BR>as they age, they can become insanely, incredibly false. This I would<BR>attribute to the deterioration of the bearing surface of the maple just<BR>behind the agraffe where the string presses into it. The strings literally<BR>crush the surface reducing the angle of deflection of the string as it exits<BR>the back of the agraffe, and an insecure termination and the falseness is<BR>the result. I have heard these problems on a number of these agraffed<BR>sohmers, mostly the (stupid) cupid grands. So I attribute that to a flaw of<BR>the design rather than an isolated incident.<BR><BR>Living in New England, I am in a harsh environment for pianos with dry<BR>winters and humid summers, so perhaps I see more deterioration than you
do,<BR>in your more benign environment. <BR><BR>Will Truitt <BR><BR><BR></td>
