ENGLISH
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 chan-
nel 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: LEVEL: Use this control to adjust the out-
put level of the Overdrive channel.
4. 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 medi-
um overdrive.
5: LEVEL: Use this control to adjust the out-
put level of the Clean channel.
6: LOW: Use this control to adjust the bass
response of the amplifier. Rotating the control
counterclockwise reduces the low frequency
output. Rotating the control clockwise increas-
es the low frequency output. It may be neces-
sary to reduce the Low frequency output at
higher volume levels.
7: MID: Use this control to adjust the
midrange frequency output of the amplifier.
Rotating the control counterclockwise
reduces the midrange frequency output.
Rotating the control clockwise increases the
midrange frequency output.
8: HIGH: Use this control to adjust the high
frequency response of the amplifier. Rotating
the control counterclockwise reduces the high
frequency output. Rotating the control clock-
wise increases the high frequency output.
