CAUTION: To avoid possible damage to your hear-  
ing, do not use headphones for extended periods  
of time at extremely loud levels.  
1: INPUT: Use this jack to connect your guitar to  
the amplifier by means of a shielded instrument  
cable.  
12: SPEAKER: Use this jack to connect the  
amplifier to an external speaker. The internal  
speaker is disconnected when this jack is used.  
The impedance of the external speaker must be 4  
ohms or greater.  
SOLO 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 Solo channel.  
3: LEVEL: Use this control to adjust the output  
level of the Solo channel.  
WARNING: Do not attempt to use headphones in  
the Speaker jack! Permanent hearing damage  
could result!  
4: SOLO/CLEAN: Use this switch to select the  
Solo or Clean channel. With the switch in the out  
position, the Clean channel is selected. When the  
switch is depressed, the Solo channel is selected.  
13: POWER: Use this switch to turn the amplifier  
on (top of the switch depressed) and off (bottom of  
the switch depressed). The switch illuminates  
when the amplifier is turned on.  
CLEAN CHANNEL: A normal gain channel  
designed to give you crystal clear sounds to medi-  
um distortion.  
14: POWER CORD (rear panel, not shown):  
The grounded power cord should only be plugged  
into a grounded power outlet that meets all appli-  
cable electrical codes and is compatible with the  
voltage, power, and frequency requirements stat-  
ed on the rear panel. Do not attempt to defeat  
the safety ground connection.  
5: VOL: Use this control to adjust the output level  
of the Clean channel.  
6: LOW: Use this control to adjust the low fre-  
quency level of the amplifier.  
7: MID: Use this control to adjust the midrange fre-  
quency level of the amplifier.

the output from a CD player or tape deck to the  
amplifier. The signal at these jacks is combined  
into a mono signal which is sent to the internal  
power amp circuit. Use the CD or tape player’s  
output level control to adjust the signal for the  
proper mix with your guitar.
