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.
 
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.
 
Hope this is helpful.


Yes, indeed. Thanks, Scott. It appears my client's serial # falls within. She 
is Korean, and has recently returned from a trip there. I think she might 
have obtained new ones. That would be great, as the recent reports of parts 
orders through YCA have not been encouraging.
