Front Panel 1 INPUT JACKS - LOW AND HIGH Connect the output of your guitar to one of the 1/4”input jacks with a shielded guitar cable. Select LOW for normal, or HIGH for extra gain. Plugging into the LOW input will attenuate your guitar’s signal cooling down a “hot” guitar. These two jacks provide slightly different input levels. Experiment with these and adjust to your tastes. 2 PREAMP GAIN - DRIVE Turning this knob clockwise determines the amount of gain (or distortion) added to the signal.
9 PHONE (HEADPHONE) jack Plugging your headphones into this jack disconnects the sound going to the speakers and allows you to practice in private. Engage the Speaker Sim Button (Point 8) for a “model” of the internal speaker. NOTE - When using with CD inputs be sure to turn the Levels down on both channels before unplugging headphones - see CD INPUT section next page. 10 POWER switch & LED Turns the amp ON and OFF. When the LED is lit, the amp is on.
Back Panel 1 GND LIFT Switch This switch electrically references the chassis to correct the line phase in the instance where the AC wall outlet may not be properly grounded. Set the switch to the postion that provides the least amount of “hum”. 2 POWER INLET Module The Power Inlet module accepts the detachable power cord included with the unit. 3 CHAN/EFX FOOTSWITCH (Footswitch) Jack To control CHANNEL selection, plug a single footswitch* into this jack.
