<<Does your piano have the vertical grain wedge? If so, get rid of it.>> This is a two-year C7F Disklavier <<The older Yamahas used trichord wedges made of felt with a vertical grain orientation. It was very easy to get positive damping with this felt initially, but it became string cut rather quickly and was more problematic with the wheeze >> Agreed. As soon as the string had cut a ledge into the verital grain, the wedge shape was lost. <<Also, polishing strings with polita might alleviate some of the problem>> Nice shiny new wire........!
