I have one of these, bought brand new in 1999 for £350 ish,there were 3 left reduced to clear at the time in fairdeal in brum.
They were a short run made in that year only from what little info I've found on them, as chilliwailer said, they are a mix of parts from US and mexico, the whole lot being finished, assembled etc in the USA factory, I changed the pickguard on mine to standard jazz config, as i never liked the all over white one, changed the pots for full size CTS ones, as it had those mini pots fitted as standard, otherwise it's stock, the neck is superb and the body is very resonant.
I'd never part with mine, was my first proper good quality bass, and still puts some US standards to shame in terms of fit and finish, the others i've come across have all had good reviews, and seem consistent. snap his hand off, I would.
