STRING SELECTOR
When
using the
guitar
and synthesizer sounds
simultaneously (Guitar Controller
BALANCE
control
somewhere
near center),
the
STRING
SELECT
switches can be used to
determine
which
strings are to
produce
the synthesizer
sounds. There
are six switches,
one for each
string.
Only those switches that
are
ON
will
produce synthesizer sounds. These switches
can be used where
it is
desired to play
a
melody
or
a
bass
line
against guitar chords, for
example,
or for other effects
where
the synthesizer notes
are
to be
relatively
independent
of the guitar
notes.
DISTORTION
There
is
one more
switch on the Guitar Con-
troller left
to be explained. With
this
switch
at
the
VCO
position (pointing
towards the
bridge),
the
VCO
synthesizer
sound
is
produced.
When
changed
to point
in
the opposite direction, the
HEXA-DISTORTION
effect
is
produced. At
center, both synthesizer and distortion sounds
are produced.
The GR-300
distortion
is
different
from
ordinary
guitar distortion
in
that there
is
a
separate
dis-
tortion circuit for each of the
six
guitar strings
thus producing an unusually
clear distortion
effect even
when
chords are played. This sound
is
also
passed through the
VCF
where the tone
color can be
further processed.
Try the
VCO
DISTORTION
sound.
