APPLIANCE TO RAIN OR MOISTURE BEFORE USING THIS APPLIANCE.
READ BACK COVER FOR FURTHER WARNINGS.
HIGH GAIN INPUT (1)
Used for most electric guitars. Itia 6
dR louder than the Low Gain input.
LOW GAIN INPUT (2)
Provided for instruments that have
extremely high outputs, which can
result in overdriving (distorting) the
High Gain input. If both inputs are
used simultaneously, the output
levels are the same (both are Low
Gain).
LEVEL (3)
Controls the volume level of the
normal channel and is not affected
by the SuperSat'" or Post Gain
controls.
BRIGHT SWITCH (4)
Provides a preset boost (+6 dB) to
treble frequencies. To activate, de¬
press the switch to its “in’ 1 position.

LINE CORD (15)
(120V products only)
For your safely, we have in¬
corporated a 3-wire line (mains)
cable with proper grounding
facilities. It is not advisable to
remove the ground pin under any
circumstances. If it is necessary to
use the equipment without proper
grounding facilities, suitable
grounding adaptors should be used.
Less noise and greatly reduced
shock hazard exists when the unit is
operated with the proper grounded
receptacles.
KEMOTE SWITCH JACK (16)
Provided for the connection of the
optional remote foots witch. Foot-
switch is used to select the Lead or
Normal channels and defeat reverb.
When using remote footswitch,
always insert the plug fully (second
click) to ensure proper operation.
