GX-40M GUITAR AMPLIFIER
Congratulations!
You are now the proud owner of the compact but powerful Crate GX-40M amplifier.
Featuring a “Clean” channel with a 3-band EQ and Level control, and an “Overdrive”
channel with our patented “Flex-Wave” circuitry with Gain, Level and Crate’s Shape
control, plus Chorus and Reverb, The GX-40M offers you more flexibility and perform-
ance than any amp in its class. Aspecial 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-40M is Musician Made in the U.S.A., using only the
best components. Extensive testing at the hands (and ears) of skilled technicians and
musicians 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

1: INPUT: Connect your guitar here
using a shielded instrument cable.
OVERDRIVE CHANNEL: A high gain
channel giving you sounds from a
slight edge to serious overdrive.
2: GAIN: This control sets the amount
of compression and distortion from
the amplifier. With the control towards
far left, the sound will have a thick
compressed quality. As you turn the
control to the right the amount of dis-
tortion increases. Crate’s exclusive
“Flex Wave” circuitry uses sequential
cascading gains to deliver distortion
which is rich in harmonics and “touch
sensitive.” Use this control along with
the Shape and Level controls (#3 and
4) to create a wide variety of sounds.
3: SHAPE: To quickly “dial in” just the
right distortion sound, simply rotate
the Shape control until you find the
sound you’re looking for. Adjusting the
“shape” of the distortion wave pro-
duces a wide variety of tone combina-
tions, allowing you to tailor the sound
to best suit your needs. In essence,
turning the control towards the left
enhances the mid frequencies; turn-
ing it to the right enhances the low
and high frequencies.
4: LEVEL: This control sets the out-
put volume level from the Overdrive
channel: in the far-left position there
will be no output; as you turn the con-
trol to the right the output increases.
Use this control along with the Gain
control (#2) to create a wide variety of
sounds.
5: OVERDRIVE SELECT: When this
pushbutton switch is pressed in the
Overdrive channel is engaged. The
clean channel is selected when this
switch is out. A footswitch (see #14)
overrides this switch.
CLEAN CHANNEL: A normal gain
channel designed to give you crystal
clear sounds to medium distortion.
6: LEVEL: This control sets the out-
put volume level from the Clean chan-
nel: in the far-left position there will be
no output; as you turn the control to
the right the output level increases.
The far right setting is maximum out-
put - as you increase the level, roll
back the Low control (#7).
7: LOW:Adjust the low frequency out-
put level with this control: turning the
control to the left reduces the low fre-
quency output; turning it to the right
increases the low frequency output.
The Low control allows a total range
of 25dB of boost or cut at 80Hz. Due
to the massive amount of low end
available, you may want to “roll off”
the bass at high volumes.
8: MID: Adjust the mid frequency out-
put level with this control: the center
position is “flat” (no boost or cut).
Turning the control to the left reduces
the midrange output; turning it to the

right increases the midrange output.
The Mid control allows for 19dB of
boost or cut at 900Hz.
9: HIGH: Adjust the high frequency
output level with this control: in the
center position the high frequency
output will be “flat” (no boost or cut).
Turning the control to the left reduces
the high frequency output; turning it to
the right increases the high frequency
output. The High control allows a total
range of 23dB of boost or cut at 5kHz.
10: REVERB: Adjust the amount of
Reverb effect with this control: in its
full-left position the signal will be “dry”
(without any reverb). As you turn the
control to the right the amount of
reverberation increases.
11: CHORUS ON: To activate the
Chorus effect, press this switch in.
(This switch is disabled when a
footswitch is plugged in – see #14)
12: DEPTH: Adjust the overall
amount of chorus with this control: to
the left for slow, smooth “phasing”
sounds, to the right for faster “vibrato”
sounds.
13: RATE: Adjust the speed of the
chorus effect with this control: to the
left for a little effect, to the right for a
lot.
14: FOOTSWITCH: Plug a dual
footswitch (such as the Crate CFP-2)
here to control channel selection and
chorus on/off. (Tip = channels, ring =
chorus, sleeve = ground.)
15: HEADPHONES: For private prac-
tice sessions, plug a pair of stereo
headphones into this jack. The inter-
nal speaker is disconnected whenev-
er headphones are being used.
16: EXTERNAL SPEAKER: You may
connect the GX-40M to an external
speaker with a rated impedance of at
least 4 ohms using this jack. The
internal speaker is disconnected
whenever an external speaker is
used.
17: ON LED: The word “ON” will glow
when you turn on the GX-40M, show-
ing you that the amplifier is activated
and ready to play.
18: POWER: This heavy-duty rocker-
type switch is used to turn the amplifi-
er ON in the up position, off in the
down position. The ON LED (#17)
works with this switch as a visual indi-
cator.
19: POWER CORD: (Rear panel, not
shown: This heavy-duty, grounded,
three-wire power cord is to be
plugged into ONLY a safely-wired,
grounded 120 volt, 60 cycle AC power
outlet. DO NOT attempt to defeat the
ground connection of this cable!
WARNING: DO NOT attempt to use head-
phones in the Speaker jack! Permanent
hearing damage could result!
