Check my thread, NPD Finally. I put a couple of clips up of it. It's a great sounding silicon fuzz.
In the lower strings at the lower frets, there are suboctaves if you back off the volume a bit and use a lighter touch. Picking over the neck pickup tends to bring thus out more too.
Middle of the neck is where the ring mod stuff seems to happen and above the 12th fret there is almost an upper octave thing going on although I haven't quite figured out how to make these stand out like the suboctaves. It's definitely got that Jimmy Hendrix vibe going on because you can hear a bit if a whooshing modulated sound on sustained notes.
Chords with Higher fuzz levels are almost synth-like. Lower gain settings, it's like a really thick sounding overdrive. It's really responsive to volume control adjustments on the guitar too.
