Congratulations and thank you for choosing the Crate GT10 Guitar Amplifier.
This rugged amplifier provides you with serious clean and distorted sounds. The
front panel features an Insert jack for virtually noise-free connection of your favorite
effects and a Headphones jack which lets you practice in private.
In order to get the most out of your new amplifier, we strongly urge you to read this
manual before you begin playing.

1: INPUT:Connect your guitar to this jack by means of
a shielded instrument cable.
2: OVERDRIVE LEVEL: Use this control to increase
the volume and add “crunch” to your sound. This control
is only active when the Overdrive Gain control (#3) is
turned on. (For more information please see the section
entitled “Getting Your Sound.”)
3: OVERDRIVE GAIN: Use this control in conjunction
with the Overdrive Level control (#2) to add distortion to
your sound. (For more information please see the section entitled “Getting Your Sound.”)
4: CLEAN MASTER LEVEL:Use this control to set the
overall output level of the amp. (For more information
please see the section entitled “Getting Your Sound.”)
5: LOW: Use this control to adjust the output level of the
low frequencies. Rotating this control counter clockwise
reduces the low frequency output; rotating it clockwise
increases it.
6: MID: Use this control to adjust the output level of the
midrange frequencies. Rotating this control counter
clockwise reduces the midrange frequency output; rotating it clockwise increases it.
7: HIGH: Use this control to adjust the output level of the
high frequencies. Rotating this control counter clockwise
reduces the high frequency output; rotating it clockwise
increases it.
8: INSERT: Use this jack to connect an external effects
to the amplifier. Use a stereo 1/4” male Y-cord: ring =
send, tip = return, sleeve = ground. Send goes to the
effect’s input; return comes from its output. (For more
information please see the section entitled “Connecting
to the Insert Jack.”)
9: HEADPHONES: Use this jack to connect a pair of
stereo headphones for private listening. The external
speaker is disconnected when headphones are in use.
10: POWER LED: This LED will illuminate when power
is applied to the amplifier.
11: POWERSWITCH: Use this switch to turn the amplifier on and off.
12: ACLINE IN: (Rear panel, not shown) The grounded power cord should only be plugged into a grounded
power outlet 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.
Getting Your Sound: The Level, Gain and Master
Level controls (#2, 3 & 4) can be used together to create a wide variety of sounds. The following guidelines
will help you achieve your desired sound.
Clean Sounds: Set the Gain control to “OFF” (the Level
control will be inactive). Use the Master Level control to
set the output level.
“Crunch” Sounds: Set the Level control to 11 o’clock
and the Gain to 9 o’clock. Use the Master Level control
to set the output level. (The Master Level control should
be adjusted to a lower setting as the Level and Gain
controls are increased.)
Rhythm Sounds: Set the Level control around 11
o’clock and the Gain at or near “10”. Use the Master
Levelcontrol to set the output level.
Lead Sounds: Set the Level and Gain controls at or near
“10”. Use the Master Level control to set the output level.
Connecting to the Insert Jack: Use Crate’s STP201,
STP202 or STP203 stereo-to-mono Y-cord or an
adapter such as Crate’s YPP117 and 2 1/4” mono signal cables to connect to the effect as shown:
1 2 3 4 5 6 8 9 10 117
Stereo-to-mono Y-cord:
(STP201, 3'
STP202, 6'
STP203, 9')
