It is from the early series with the solid aluminium chassis. A really dumb design flaw (I utterly hate it!
) is that the boards were slid into the chassis and then a thin flexible black cover with the controls printed on it was put over the potentiometer shafts and glued to the top of the chassis. If you want to remove the boards for maintenance or repair you will inevitably destroy this cover. I wanted to treat the crackling potentiometers with tuner spray. I wanted to remove the boards, so I carefully lifted the one side of the cover ... aaargh! The label of the first potentiometer doesn't look too nice anymore. Stupid design! Why didn't they print it on a sturdy metal plate?! You also have to be careful with the printed labelling on the chassis. Avoid cleaners that contain alcohol! I wanted to remove some bits of residue - now it's an "OCKTRON" pedal. Aaargh! 
And how does it sound? Okay-ish. The octave up fuzz isn't half bad, but the octave down (octave up fuzz and the low octave can be blended with the MIX knob, each to full wet sound; the MOD knob is like a tone knob for the low octave) despite sounding nice with a very synth-like square wave tone, is just too glitchy and it doesn't work on the whole fretboard. All in all pretty much a let-down.
