The same bass strings, same notes kept breaking.</div> <div>I explained the problem I was having to the tech at Mapes who was making the replacement strings, Mapes has the scalings for Kawai's from Kawai.</div> <div>His suggestion was to re-engineer the string with a slightly thicker core wire and slightly thinner wrap arriving at the same string outer dimension but a stronger string.</div> <div>It worked.</div> <div> </div> <div>Mike<br>-- <br>I feel sorry for the person who can't get genuinely excited about his work.
