I have a customer with a Kawai GS-70. After it arrived about three years ago treble strings started to break while playing, about once every 2 to 3 weeks. I talked to Kawai techs and decided to restring the capo section. I used Kawai's stringing chart for decimal wire and sanded the capo to shiny smooth. I also filed the hammers. After a short while strings started to break again every month or two. Now they are breaking about one every 2 to 6 weeks. The breaks have always been at the capo. What am I overlooking? I would not say the players strike overly hard. It is in a private school. Students and teacher (mostly teacher) have broken wire. Classical music. Could hammer position have a bearing here? Hammers are original. Regulation? I need some brainstorming here! Many thanks, Daniel Berg RPT -------------- next part -------------- An HTML attachment was scrubbed...
