I think UFO stands for "Ultimate Fuzz Octaver." You can hear it around minute 6 of this video:

Anyways, this thing kicks much ass and I may just need to drop the $160 on it. Seems like a very reasonable price for a hand-built pedal. I like the sound of octave fuzz but I find most pedals just get too out of control. With the UFO it seems like you could play chords with the octave on or off and stil have the tone speak though. Plus it just sounds really nice.
