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
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: LEVEL: Use this control to adjust the
output 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
medium overdrive.
5: LEVEL: Use this control to adjust the
output level of the Clean channel.
6: LOW: Use this control to adjust the bass
response of the amplifier. Rotating the con-
trol counterclockwise reduces the low fre-
quency output. Rotating the control clock-
wise increases the low frequency output. It
may be necessary to reduce the Low fre-
quency 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 clockwise increases
the high frequency output.
