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!

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.
