Ah, the Stick. Tony Levine, who's rather a fine bassist, plays it on some of Peter Gabriel's stuff. Unfortunately it doesn't sound as remarkable as it looks.

I don't know about folk, but I did once see someone busking with a Stick. I wish I'd stopped to see what he was *doing* with it - the guy in the Youtube clip appears to be fingering one set of strings and plucking another, which (I'm no guitarist, but) it seems to me wouldn't generally work terribly well.
