THE
MUSIC TRADE
REVIEW
FEBRUARY 27, 1926
Accuracy
like the great musician's fingers
timed exactly to his will
So is the SIMPLEX Unit Valve—sensitive to
the slightest air pressure—adjusted for action
to the thousandth of an inch—once set at our
factory, it will never again need to be changed
or adjusted.
That's the reason why the SIM-
PLEX (unit type) PLAYER
A C T I O N is Dependable —
Mechanically accurate, operating
with sympathetic ease.
Testing the valve action—Each
must register 28/1000 of an inch
Other accurate features are the
SIMPLEX trapezoid tracker
bar, the automatic roll adjust-
ment and transposing device.
Assembling the SIMPLEX 4-
piece valve—most other valves
contain as many as 25 pieces.
Piano Manufacturers and Dealers
have learned by experience that to specify SIMPLEX Unit Type PLAYER ACTION—means better response
with less effort, easy adjustment, fewer parts, less repairs. Catalog describing pedal operating and repro-
ducing player actions sent on request.
