RicB's comment about 'adding mass' to the bridge pin by pushing (for instance) a screwdriver blade against, it or on top of it, suggests that maybe thicker/longer/heavier bridge pins may work better in the top regions. Even the lightest pressure on my Bechstein 'B' top treble bridge pins eliminates the false beating. Translating this into permanancy is the next question. I currently tune a Stuart piano where this type of falseness is unknown. OK, the construction of these instruments is very different, but there is certainly a considerable amount of 'mass' in the bridge aggraffes through which the strings pass. Is this a clue? ric ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
