ominous bear

If it helps, I've just weighed the one I have (that exact model) and it's 9.1 lbs / 4.13 kg. Oh, and the pickups are nowhere near jazz shape, but sound pretty decent to my ears.

I bought one B stock, for exactly the same reason as you. Really nice bass and an absolute bargain even at full price. Assumed I'd end up buying a more expensive FL 5er if I liked it, but no need and would need to spend loads more to step up. Needed shielding and a good set up (particularly nut slots), plus the neck benefited from a sand, cos you could feel the joins between the different woods. But a cracking playing, decent sounding bass.
