You are now the proud owner of the compact but powerful Crate GX-15/15R amplifier. Two
versatile channels -“ one crystal clear and the other with our patented Flex-Wave distortion -“
combined with reverb (GX-15R) and a three-band EQ offer you more flexibility and perform-
ance than any amp in its class. A special damping circuit simulates the current source type of
output of a tube amp, giving you solid state reliability combined with classic tube sounds.
Like all Crate products, your GX-15/15R is designed by musicians, and built using only
the best components. Extensive testing insures you that this amplifier is the absolute best
it can be.
In order to get the most out of your new amplifier, we strongly urge you to go over the
information contained in this manual before you begin playing.
And thank you
for choosing

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 counterclockwisereduces 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.
10: HEADPHONES:Use this jack to con-
nect headphones to the amplifier. The
internal speaker is disconnected when this
jack is used. A line level signal can also be
obtained from this jack for recording, etc.
CAUTION: To avoid possible damage to
your hearing, so not use headphones for
extended periods of time at extremely
loud levels.
11: EXTERNAL SPEAKER:Use this jack
to connect the amplifier to an external
speaker. The internal speaker is discon-
nected when this jack is used. The imped-
ance of the external speaker must be 4
ohms or greater.
WARNING: Do not attempt to use head-
phones in the Speaker jack! Permanent
hearing damage could result!
12: ON LED:This LED illuminates when
the amplifier is turned on.
13: POWER:Use this switch to turn the
amplifier on (top of the switch depressed)
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.
