Sohmer

[Newton Hunt]

Turn them suckers!!  Care must be taken when backing out
pressure bar screws, they can break easily because of the
pressure they are under.  There should be just enough
deflection of the wire to prevent it from dancing upon the
v-bar with a hard blow.  Any more than that is unnecessary
and undesirable.  Changing the angle of deflection with NOT
change tone or volume and very well improve tunability.

Sohmer 45S uprights do not stay well in tune.  The middle
section goes radically out of tune when the humidity
changes.  You may consider installing a climate control
system to stabilize the piano.  Worked for me.
