<div>As I recall, the serial #'s with that particular problem ran from about G091500 to G0103999. I believe Phil Glenn told me that they went back to brass at 104000, but with the existing profile. The originals can be retrofitted with the brass, but the one time I did it, it was very tough to get the existing inserts out. Phil told me, however, that he had not noticed any particular problem with the removal. I don't know if Young Chang would still have the replacement inserts, or what difficulties you would have in obtaining them.</div> <div> </div> <div>I have not experienced any particular string breakage problem with these-at least none that I wouldn't attribute to the rock-hard and unshaped hammers frequently encountered or excessively heavy playing.</div> <div> </div> <div>Hope this is helpful.</div> <div> </div> <div>Scott Nelson, RPT<BR><BR><B><I>BobDavis88@aol.com</I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px;

Also, can these, or any other insert used by YC, contribute to string breakage? I am about to restring a model 213, serial G099xxx, which <STRONG>eats</STRONG> treble wire.
