ENGLISH
1: INPUT: Use this 1/4” jack to connect
your guitar to the amplifier by means of a
shielded instrument cable.
OVERDRIVE CHANNEL: A high gain
channel giving you sounds from a slight
edge to serious overdrive.
2: GAIN: Use this control to adjust the
amount of distortion for the Overdrive
channel.
3: LEVEL: Use this control to adjust the
output level of the Overdrive channel.
4. OVERDRIVE SELECT: This switch,
when depressed, selects the Overdrive
channel. The Clean channel is selected
when this switch is in the out position.
CLEAN CHANNEL: A normal gain channel
giving you sounds from crystal clean to
medium overdrive.
5: LEVEL: Use this control to adjust the
output level of the Clean channel.
6: LOW: Use this control to adjust the bass
response of the amplifier. Rotating the con-
trol counterclockwise reduces the low fre-
quency output. Rotating the control clock-
wise increases the low frequency output. It
may be necessary to reduce the Low fre-
quency output at higher volume levels.
7: MID: Use this control to adjust the
midrange frequency output of the amplifier.
Rotating the control counterclockwise
reduces the midrange frequency output.
Rotating the control clockwise increases
the midrange frequency output.
8: HIGH: Use this control to adjust the high
frequency response of the amplifier.
Rotating the control counterclockwise
reduces the high frequency output.
Rotating the control clockwise increases
the high frequency output.
9: REVERB LEVEL (GX-15R only): Use
this control to adjust the amount of reverb
applied to the output signal.

your hearing, so not use headphones for
extended periods of time at extremely
loud levels.
11: EXTERNAL SPEAKER: Use this jack

and off (bottom of the switch depressed).
14: POWER CORD (rear panel, not
shown): The grounded power cord should
only be plugged into a grounded power out-
let that meets all applicable electrical codes
and is compatible with the voltage, power,
and frequency requirements stated on the
rear panel. Do not attempt to defeat the
safety ground connection.
