Sohmer

[Tom Driscoll]

I  service a Sohmer 45S in a New England school  .  My experience with this
piano concurs with Newtons. Pitch fluctuates  wildly in tenor with humidity
changes . climate control was of minimal benefit. As for pressure bar
adjustment , tunability can be improved  I'm sure, but the dominating factor
with this model is the instability. Question? Is this a soundboard -
rib-backpost design flaw? I've been all over this piano and can't find
anything wrong. Tom Driscoll
