Yea, Nigel, we're having a ball with the one in the office! Actually think you could play a light jazz or bluegrass gig with one and a good amp.
I'm getting two more kits for a summer music camp run by the public schools system. I know one of the instructors, who will help students assemble and play one in each of the two remaining sessions. It's kind of like a poor mans upright with a pick-up. You can experience something very close to a real acoustic bass amplified.
Cool little silly, but educational toy!
