Had one a wee while back. From what I recall, the body was slightly oversized, compared to an Epiphone / Gibson, and it has a 44mm nut (opposed to 38mm on the Epiphone / Gibson models). The oversized body meant that it won't fit into a shaped T'bird case, but does fit into a gig bag.
Other than that, it's a solid bass. Prone to the usual T'bird complaints of course. I didn't find it head heavy, but you have to have long arms (especially if you want to play it sat down!). If you play with it on a strap, then you need to have the body resting on the hip rather than having the body resting across you (as you would with an FSO for example).
