Hi Jim,

I had a similar experience with a Kawai KG-2  (very similar looking to a
500) also in a church. The same bass strings, same notes kept breaking.
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.
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.
It worked.

Mike
