Does anyone know where I can find some information on this bass? I'm very interested in them, but I can't find anything about them. It seems like it'd be a perfect fit for me. Just a couple of weeks ago, I was playing a 4003, wishing it came in a 5 string version, and now I find out they make them. Have they been discontinued? If not, where could I find one, and what's the going price on one?
