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 com-
pression 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 distortion 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 Level (#3) to cre-
ate a wide variety of sounds.
3: LEVEL: This control sets the output volume
level from the Overdrive channel: in the far-left
position there will be no output; as you turn the
control to the right the output increases. Use this
control along with the Gain control (#2) to create
a wide variety of sounds.
4: OVERDRIVE SELECT: When this pushbutton
switch is pressed in the Overdrive channel is
engaged. The clean channel is selected when
this switch is out.
CLEAN CHANNEL: A normal gain channel
designed to give you crystal clear sounds to
medium distortion.
5: LEVEL: This control sets the output volume
level from the Clean channel: in the far-left posi-
tion there will be no output; as you turn the con-
trol to the right the output level increases. The far
right setting is maximum output - as you increase
the level, roll back the Low control (#6).
EQUALIZATION
6: LOW: Adjust the low frequency output level
with this control: turning the control to the left
reduces the low frequency 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.
7: MID: Adjust the mid frequency output 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.
8: 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.
9: 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.
10: CHORUS: The GX-25M features a built-in,
preset Chorus effect to enhance the sound of
either the Overdrive or the Clean channel. Press
the Chorus switch IN to activate the effect.
11: HEADPHONES: For private practice ses-
sions, plug a pair of stereo headphones into this
jack. The internal speaker is disconnected when-
ever headphones are being used.
12: EXTERNAL SPEAKER: You may connect
the GX-25M 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.
13: ON LED: The word “ON” will glow when you
turn on the GX-25M, showing you that the ampli-
fier is activated and ready to play.
14: POWER: This heavy-duty rocker-type switch
is used to turn the amplifier ON in the left position,
off in the right position. The ON LED (#13) works
with this switch as a visual indicator.
15: 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!
