I spent a good few hours dickinga round with one, and R really liked it, it has so many possibilities...you can even play "drums" on your guitar, with different strings corresponding to dif drums...I was gonna buy one, but like Rockonn said, it said to be too much of a niche pedal...when I used it in songs it would sound great, but I hoenstly didnt think I'd use it in too many songs...

that said, I am thinking of getting one now, and recording all of the parts on to my Jam man, and looping them live.
