If you are thinking of going for a G&L WOT, this is a useful link:

I've had two USA G&L's, an SB1 which is my main gigging bass and an SB2, which I recently sold on here. Both excellent but 1980's vintage instruments with different controls to the current models, so maybe not relevant to your question.
My SB1, although passive, is certainly a turbo charged Precision. The MFD pups in the USA models are very, very hot.
The SB1 weighs 9lb 4oz and the SB2 9lb.
The bridges are very substantial and a breeze to adjust and lock.
The neck plate, although only the three screw variety is perfectly stable and also has the neck tilt adjustment, to save on faffing with shims.
A couple of pics down below. The SB1 is the white one.
