[pianotech] Kawai electric piano breaking bass strings.

[Ken & Pat Gerler]

Mike,
As John said, Mark Wisner, Kent Smith, and Juan Escobar at Kawai should be 
able to get you the proper/current information and strings for the piano. 
They are all good people!

I personally have never had an "opportunity" to work on one of these models.
