OPERATION OF CONTROLS AND CONNECTIONS, continued
8 DISTORTION CONTROL
This control is used to create a desired amount of distortion. Distortion is somewhat similar to the sound
effect known as "fuzz." When the distortion control is turned fully counter clockwise,
the distortion circuit is
bypassed. To obtain the desired distortion effect, advance the control knob to the right until the desired
effect is achieved. The distortion circuit is electronically switched in and out with the foot switch while
playing. Electronic switching eliminates clicks.
9 AUXILIARY VOLUME CONTROL
This control allows you to pre-set two different volume levels: one primary and the other secondary. Use
the master Volume Control (4) to set the primary level, then press the foot switch down and set the
secondary level with the Auxiliary Volume Control. The foot switch selects
between primary and secondary
volume levels. Again, switching is done electronically, therefore there are no clicks and pops that would
interfere with your playing. This control enables the
musician to switch with ease back and forth from lead
playing to rhythm playing.
10 GROUND REVERSE SWITCH
Many times you will have a persistent hum or buzz from the guitar strings. The Ground Reverse Switch has
been designed to reduce or eliminate this condition. Set the Switch in whichever position reduces or
eliminates the problem.
11 LEAD/BASS SELECTOR SWITCH
The amplifier in the LEAD Switch position operates as a wide-band flat amplifier. It reproduces fundamental
tones plus the harmonics. This is desirable when playing a lead guitar. When the Switch is used in the
BASS position, the harmonics are restricted. Any harmonics that are more than 1200 Hz are de-
emphasized, a desirable characteristic when playing a bass guitar. The LEAD/BASS selection is made in
the output section of the circuit making the LEAD/BASS conversion effective even when the amplifier is
being overdriven or when used in a distort mode.
12 POWER ON/OFF SWITCH
This Switch turns the entire system On. There may be a moderate thump when you turn the amplifier On.
DON'T PANIC. This is normal. The "On" condition of the amplifier is indicated by the indicator light built into
the switch button.
