to get 2 basses... a Bee Thunder and... Who makes a thin body with a wide, thin neck 6 string $2500-$3000?
theres always the stinger. (don't know that price) Or you could talk to Chris Stambaugh about it Stambaughdesigns.com he's really affordable, and top quality.
Off the shelf, a Yamaha Pattitucci definitely fits the description, and it's under your price range. In the price range (and what I'd do personally in this scenario) is to get a used set-neck Ken Smith.
