POWER SWITCH
This two-way toggle switch applies mains power to the unit. The amber power sta-
tus lamp (3) will illuminate when this switch is in the ON position.
STANDBY SWITCH
This two-way toggle switch allows the amp to be placed in the STANDBY mode.
In the STANDBY position the tubes stay hot but the amplier is not operational.
Switching to the ON position places the amp in active mode.
POWER STATUS LAMP
This indicator illuminates when mains power is being supplied to the amp.
MASTER VOLUME
This control sets the overall volume level of the amp. Once the desired balance
between the three channels in the amplier has been achieved, the entire output
level of the unit can be increased or decreased by rotating this control. Clockwise
rotation increases level; counterclockwise rotation decreases level.
TREBLE
This control, on both the Rhythm and Lead channels, varies the high frequency
response of the amplier. It is an active control (shelving type) and allows 15 dB of
boost or cut.
MIDDLE
This control, on both the Rhythm and Lead channels, varies the mid frequency
response of the amplier. It is an active control (peak/notch type) and allows 15 dB
of boost or cut.
BASS
This control, on both the Rhythm and Lead channels, varies the low frequency
response of the amplier. It is an active control (shelving type) and allows 15 dB of
boost or cut.

CHANNEL ACTIVATION LEDs
These indicators signify which channel is active. Lead channel activation illuminates
the red LED; Rhythm channel activation illuminates the yellow LED; and Clean chan-
nel activation illuminates the green LED.
TREBLE
This passive control regulates the high frequencies for the Clean channel.
MID
This passive control regulates the mid frequencies for the Clean channel.
BASS
This passive control regulates the low frequencies for the Clean channel.
INPUT
This 1/4” jack is designed to accommodate most any guitar output signal. Input sig-
nal gain can be adjusted by the GAIN (9) controls (Rhythm and Lead channels only).
CHANNEL SELECT SWITCH
This three-position toggle switch allows selection between the amplier’s three
channels. LED (10) illumination indicates which channel is active. Channel switch-
ing can also be accomplished by footswitch. See the FOOTSWITCH section of this
manual for explanation of switch operation. The CHANNEL SELECT SWITCH must be
set in the Lead position in order for the footswitch to operate properly.
