Yamaha GH-1

Mary, Scott and the list,

I recently restrung and rescaled a GH-1 for a customer.  By changing the
first four unwound trichords to wound bichords we achieved a substantial
improvement.  James Arledge assisted me on this and he does a great job
both of rescaling (he even takes longitudinal mode into account) and
winding the strings (his lathe has a tension control to assure even
winding.)

If you really want to solve the problems, this is the direction I would
recommend.

| Mary,
| 
| I will be using Pscale on this piano sometime in mid-June. I am
guessing
| that at least 4 and maybe 6 of the low plain-wire unisons in the low
tenor
| will be replaced with wound strings. I'll get back with the scaling
results
| next month. It'll be interesting to run several different what if
scenarios.
