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.
