ENGLISH
1: INPUT: Use this 1/4” jack to connect your guitar
to the amplifier by means of a shielded instrument
cable.
OVERDRIVE CHANNEL: Ahigh 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: SHAPE: Use this control to “dial in” the tone for
the Overdrive channel. Rotating the control counter-
clockwise enhances the mid frequencies, while
rotating the control clockwise enhances the low and
high frequencies.
4: LEVEL: Use this control to adjust the output level
of the Overdrive channel.
5. 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.
6: LEVEL: Use this control to adjust the output level
of the Clean channel.
7: LOW: Use this control to adjust the bass
response of the amplifier. Rotating the control coun-
terclockwise reduces the low frequency output.
Rotating the control clockwise increases the low fre-
quency output. It may be necessary to reduce the
Low frequency output at higher volume levels.
8: MID: Use this control to adjust the midrange fre-
quency output of the amplifier. Rotating the control
counterclockwise reduces the midrange frequency
output. Rotating the control clockwise increases the
midrange frequency output.
9: HIGH: Use this control to adjust the high fre-
quency response of the amplifier. Rotating the con-
trol counterclockwise reduces the high frequency
output. Rotating the control clockwise increases the
high frequency output.
10: REVERB LEVEL: Use this control to adjust the
amount of reverb applied to the output signal.
11: CHORUS: This switch, when depressed,
applies the built-in chorus effect to the output signal.
12: CHORUS DEPTH: Use this control to adjust
the amount of Chorus applied to the output signal.
13: CHORUS RATE: Use this control to adjust the
speed of the Chorus effect.
14: FOOTSWITCH: Use this jack to connect the
1/4” stereo plug on the cable of a two-button
footswitch (such as the Crate CFP-2). This allows
you to remotely switch between channels and turn
the chorus on and off. (Tip = channel select, ring =
chorus on/off.)
15: HEADPHONES: Use this jack to connect head-
phones to the amplifier. The internal speaker is dis-
connected 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.
16: EXTERNAL SPEAKER: Use this jack to con-
nect the amplifier to an external speaker. The inter-
nal speaker is disconnected when this jack is used.
The impedance of the external speaker must be 4
ohms or greater.
WARNING: Do not attempt to use headphones in
the Speaker jack! Permanent hearing damage
could result!
17: ON LED: This LED illuminates when the ampli-
fier is turned on.
14: POWER: Use this switch to turn the amplifier on
(top of the switch depressed) and off (bottom of the
switch depressed).
15: POWER CORD (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.
