I pull in unisons as I= go. 100 cents up does not come out to 25 cents flat in my= experience. More than anything, I don't like to bring the= tension to higher than pitch....phobia? probably.

If you never overpull, you will never= get up to pitch! You'll get close, but only after quite a few= passes - especially in the high treble. Why would you not want= to pull 'em a bit sharp?

Although, it will work= most of the time on most Olde Uprights and Grands, there is= always the exception. This technique is archaic, to say the= least. There are better ways. The 32% in the upper treble will= most likely get someone in a world of hurt! Most strings, in= that area, are already at/above 50% of their breaking= strength!!! You raise it another 32% and strings will break,= IMO. I've done some studying on the subject and wrote an article= for the PTJ, in Dec. 1999. Regards, Joe Garrett, R.P.T.
