Yamaha Grand GH-1

[Claude Harding]

George,
   I'm not sure if this relates to the problem you are encountering, but
this model had a problem with tonal and tuning problems at the botton of the
tenor bridge (B27, C28.....).  The plain steel wire went all the way down
through B27 on the tenor bridge, but with the short wire lengths the tension
was so low that I would sometimes compare it to trying to tune rubber bands.
    I seem to remember a time when Yamaha offered a plan to rescale those
lower notes on the tenor bridge with wrapped strings, but I don't remember
any details about that.
    I think some later versions of the GH-1 had some improvements made in
that area, although still with the plain steel wire, and the sound was
better.
   Sorry I can't be more specific -- this report reflects personal
experience but not much investigation or analysis.
If this has nothing to do with your question or problem, just disregard and
I'm sure someone else on the list will chime in.

HI folks,
I am looking for some info on the Yamaha Grand GH-1....have experienced
problems in tuning stability and was wondering if it was a common problem
with this particular model.
George
