<DIV><FONT face=Arial size=2>Hi Terry: I suppose this could be a longitudinal
mode issue, but in a sense that is not to the point. The customer wants the
offending sound cured, and I am in accordance with John Delacour in that the
only real cure is to chuck the Yamaha strings and replace them with some higher
quality ones. Of course Yamaha will not cover this cost of this, or even the
Pitch-Locks. </FONT></DIV>
