SPECIAL FEATURES
9 The GR-100 can produce, by means
of a unique electronic circuit, an
entirely new electronic sound effect
previously not possible with earlier
electric guitar models. -
®Playing the guitar is fun thanks to
the rich tone quality made by the
Hexa VCF which uses a VCF for
each string.
-®A wide range of electronic sounds
are possible from the filter modula-
tion, touch vibrato and chorus ef-
fect..
