This looks pretty nice. Will definately try one out next time I'm down Denmark St. Even if there's nothing in the box, it's such a nice design it deserves buying. I'd really like to take that mushroom switch apart to see if it's just an actuator resting on a board-mounted switch or something higher spec.
I've searched for demos and the only one I could find is some jerk playing it through a distorted amp (of course) and an awful Boss rackmount delay(!)
