[pianotech] Yamaha GB-1 string breakage

[Israel Stein]

Hello,

Today I  replaced 4 broken strings in an approximately 3-year old GB-1. 
They were in the top 3 octaves. Client said they all broke while she was 
playing the piano. She is a fairly good classical player (I know, I 
know, what is she doing with that model Yamaha - she bought it before 
she hired me...) Anyone aware of a history of string breakage with that 
model Yamahas?
