I also could feel the tension increasing too quickly, and the string snapped at the tuning pin. I asked for a replacement, and could feel the same overly rapid increase in tension. I didn't bring it up to pitch completely  because I could see that the winding was ending way too short from where it would be, as judged by comparison to the existing left unison. I am having a string made by Mapes from measurements, and hope their's does the job. I have never had this kind of problem before with any bass string. Anyone have any ideas? Bad core wire, perhaps?</FONT></DIV> <DIV><FONT size=2 face=Arial>Patrick C. Poulson<BR>Registered Piano Technician<BR>530-265-1983</FONT></DIV></BODY></HTML>
