Handling caution
Part Names/Control Descriptions
q Line Out Volume Control/TA Switch
To turn on the TransAcoustic guitar, press this knob for approximately
0.3 seconds. When a cable is connected to the TransAcoustic’s output/
line out jack, the output level can be adjusted by rotating this control to
the right (clockwise) to increase the level, or to the left (counterclock-
wise) to reduce the level.
w Reverb Control
Adjusts the reverb effect. Turning this control to the right (clockwise)
increases the level of the effect and selects between the TransAcoustic’s
two reverb types: Room and Hall (in the 12:00 position). Turning it all
the way to the left (counterclockwise) bypasses/switches the reverb
effect off.
e Chorus Control
Adjusts the chorus effect. Turing this control to the right (clockwise)
increases in the intensity of the chorus effect. Turning it all the way to
the left (counterclockwise) bypasses/switches the chorus effect off.
r Output Jack/Battery Holder
The output jack and battery compartment are combined into a single
unit. Inserting a plug into the output jack switches the internal preampli-
fier ON.
* To prolong the life of your battery, please unplug the cable from the output
jack when not in use.
LED Display Details
The LED located inside the sound hole flashes red when it is time to
change the batteries. Once the LED begins flashing, the remaining oper-
ation time is approximately two hours with alkaline batteries and about
one hour when using nickel metal hydride batteries (Time varies accord-
ing to operating conditions). Please replace the batteries as soon as
