In the GR-300, not only is the hex distortion completely separate from the 
pitch tracking, it's not even IN the GR-300.   That is to say, the blue GR-300 
synth floor unit does not have an internal hex distortion section.   Some, but 
not all, of the GR series guitars had the hex distortion circuit built into 
the guitar, with a three-position toggle switch that let you select VCO, hex 
distortion, or both as your sound source.   The G-303 and G-808 guitars (the ones 
Pat Metheny plays) had the hex fuzz, but the cheaper G-202 and G-505 did not. 
  I'm not sure about the G-707 (not that anyone in their right mind would 
ever want to be seen in public with one, except possibly as part of a costume at 
a Star Trek convention).   I think the lower-cost yellow GR-100 floor unit had 
a built-in hex fuzz, but did not include any pitch tracking or VCO's -- it 
was just a fancy hex fuzz, filter, chorus, and envelope unit.
