That's cruel. What is it, who makes it, and where can I (or can't I) get one? I think I'm gonna drill a hole in my keyboard so the drool can run out.
Rob Allen makes them, Jimmy Coppola at NY Guitar and Bass Boutique usually has a couple on hand... Check out his site when you get a chance: http://www.guitarboutique.com
Clubbass in Canada has some really nice pictures of Rob Allens in their inventory http://www.clubbass.ca/allen/allen.html
Which they don't really. If you play them without any modification to technique, they just sound like a fretless BG. If you modify your technique, you can get it to sound double-bassy, but you can do that with a normal fretless too and some flatwounds. Just think of them as fretlesses with a really clean look.
Go to the web site and take a look at the walnut burl top. Or the koa one here http://www.bunnybass.com/pictures/interview/roballen/glue_koa.jpg
