-CONTROL PANEL-
The control panel has three sections: the 12AX7 guitar pre-amp, the spring reverb controls and
the rotary motor control area.
Input: ¼” unbalanced input accepts signal from typical pickups with a maximum input voltage of
7 volts peak to peak.
Gain: Adjusts the drive level to the 12AX7. The circuit is a unique Motion Sound symmetrical
clipping topology, which provides silky smooth sound to massive overdrive. The amount of gain
depends on your pickups and knob settings on the guitar.
Pickup Gain: A small screwdriver adjustment to match pickup output to the gain control.
Increase “CW” if you need more overdrive.
Contour: This PRE 12AX7 EQ is centered at 800 Hz and cuts highs or lows before the 12AX7
tube, allowing you to set smooth, equal amounts of overdrive up and down the neck. Low cut
will stop bass notes from overdriving the 12AX7 too much. You may set the control flat or to
remove highs or lows.
Volume: Sets the overall loudness of the AR-112 by controlling the volume of the 100 watt solid
state power amplifier. A “line voltage tracking” compressor helps prevent solid state overdrive.
Base and Treble: AR-112 tone controls are classic EQ frequencies and gains commonly used on
many guitar amplifiers.
-REVERB-
Volume: The AR-112 utilizes a classic dual spring reverb tank mounted on isolation foam. The
volume is set to preference. Under extreme circumstances, such as the reverb volume at “10” and
the AR-112 tilted, there may be some reverb feedback. Try to avoid these extremes.
Tone: This control centered at 700 Hz allows emphasis of the reverb tone to be high or low as
needed.
-ROTOR-
Slow: This sets a range of liquid chorus effects from very slow to modulating midrange. Set the
slow control FIRST (the fast speed is added to the slow settings).
Fast: After setting slow, the first speed operates from mid-speed through fast classic rotary
tremolo speeds.
Accel: Acceleration (the time it takes to go between the fast and slow settings) is adjustable from
a short time = “10” to a longer time = “1”.
-LED FOOTSWITCH-
Fast/slow: When the LED is “on”, the rotor will accelerate and run at the fast control setting
(remember to set “slow” speed FIRST).
