Important Safeguards and Precautions:
All Crate products are designed for continuous safe operation.
Abiding by the following rules can help prevent damage to your
amplifier, yourself and others.
• The amplifier is equipped with a three-pronged AC power
cord. To reduce the risk of electrical shock, NEVER remove
or otherwise attempt to defeat the ground pin of the power
cord.
• Connect the amplifier ONLY to a properly grounded AC
outlet of the proper voltage for your amp.
• Avoid sudden temperature extremes, rain and moisture.
Also, avoid sudden and intense impact. (If the unit has
been subjected to any of the preceding abuses, have it
looked at by an authorized service center.)
• Do not expose the unit to splashing or dripping liquid. Do
not place liquid filled objects on the unit.
• NEVER set the amplifier on a support that will not bear its
weight.
• Always keep the total speaker impedance at or above the
rated load.
• Unplug the amplifier before cleaning it. NEVER spray liquid
cleaners onto the amplifier. Wipe it with a slightly damp-
ened, lint-free cloth to remove dirt and film.
• DO NOT use the amplifier if it has sustained damage to the
chassis, controls, or power cord. Refer the unit to an
authorized service center for inspection.
• Prolonged exposure to high volume levels may cause per-
manent hearing loss or damage. Such damage is progres-
sive and irreversible!

The Front Panel:
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. With the control counter clockwise, the sound will have a thick com-
pressed quality. As you rotate the control clockwise the amount of distortion
increases.
3: LEVEL: Use this control to adjust the output level of the Overdrive channel.
4: CHANNEL SWITCH: Use this switch to select either channel. With the switch
in the out position, the Clean channel is selected. When the switch is depressed,
the Overdrive channel is selected.
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 full counterclockwise position there will be no output; as you rotate the con-
trol clockwise the output level increases. The full clockwise setting is maximum
output - as you increase the level, roll back the Low control (#6).
EQUALIZATION:
6: LOW: Use this control to adjust the low frequency level of the amplifier. Due to
the massive amount of low end available, you may want to “roll off” the bass at
high volumes.
7: MID: Use this control to adjust the midrange frequency level of the amplifier.
8: HIGH: Use this control to adjust the high frequency level of the amplifier.

9: REVERB LEVEL: Use this control to adjust the amount of reverberation: in its
full counter clockwise position the signal will be “dry” (without any reverb). As you
rotate the control clockwise the amount of reverberation increases.
10: CHORUS: This switch, when depressed, activates the built-in, preset chorus
effect to enhance the sound of either channel.
11: HEADPHONES: Use this jack to listen to the amplifier through a pair of stereo
headphones. The internal speaker is disconnected when the headphones jack is
used.
CAUTION: To avoid possible damage to your hearing, do not use
headphones for extended periods of time at extremely loud listening
levels.
12: EXTERNAL SPEAKER: Use this jack to connect the amplifier to an external
speaker. The internal speaker is disconnected when this jack is used. The mini-
mum impedance for the external speaker is 4 ohms.
13: ON LED: This LED will illuminate when power is applied to the amplifier.
14: POWER: Use this switch to turn the amplifier on and off.
15: AC LINE CORD: (Rear panel, not shown:) This grounded power cord is to be
plugged into a grounded power outlet, wired to current electric codes and compatible
with voltage, power, and frequency requirements stated on the rear panel. Do not
attempt to defeat the safety ground connection.
