Top-mounted, Spring Adjuster Arm
Beater Position Adjustments
The Beater of the Dyno-Matic
Pedal can be positioned
independently - without affecting
the positions of the Pedalboard, the
Spring Arm, or the Axle height. The
forward, or backward angle of the
Beater Cam is adjusted by loosening
the Beater Angle Screw with the Drum
Key, as shown on the left. The
length of the Beater shaft can be
changed by loosening the
Beater Length Screw with
the Drum Key, as
shown on the right.
Be sure to tighten the
screws securely once
positioned.

The Dyno-Matic
features a modern
upgrade to one of
Rogerʼs original pedal
innovations - the
top-mounted Spring
Adjuster Arm. While
playing the pedal, you
can easily reach from
your playing position to
adjust the spring action
with one hand.
First loosen the Lock
Nut by turning clock-
wise. Then adjust the
Finger Nut to loosen,
or tighten the spring to
achieve the desired
ʻfeelʼ. Then, turn the
Lock Nut counter-clock-
wise to set the position.
