CONTROL OPERATION
CHANNEL I - LEAD
The Kustom
IV
Lead
electric guitar amplifier
is
designed with one
of
the most flexible
electronic control systems available.
The Channel I preamplifier includes a non-linear device which
can
be
used
to introduce a
deliberate, controlled distortion into the music. Located
in
the circuit between the DRIVE
and
VOLUME controls, the device receives its signal from the DRIVE circuit.
In
this manner, a high
DRIVE setting causes more distortion, independent
of
the VOLUME setting. As a result, the
VOLUME setting to produce a given output will depend
on
the DRIVE control setting. DRIVE
and
VOLUME controls should
be
used
together to obtain a type
of
distortion similar to certain older
tube-type amplifiers.
To
achieve this sound, adjust both controls
so
that the desired amount of
distortion
is
achieved at the required volume level. With the DRIVE control adjustep maximum
counter-clockwise, distortion will
be
at a minimum.
Distortion occurs
in
the preamplifier and not
in
the output or final stages. Output distortion
will
be
obtained only at high power and volume levels and
has
a distinctly different sound.
