Yep, the bodies and hardware were US, painted in Mexico and assembled in Corona, CA. Mine with the P PUP soloed sounded very very close to my '83 VS '62 P. V/V/T like a Jazz bass, the neck was a bit more narrow than a P, but not stupid skinny like a Geddy Lee. Great electronics, fit and finsih, fret dressing, etc. Only weak spot for me was the tuning machines which I thought were sloppy and coarse. I put a set of Hipshots on mine and it was a great stage bass for me. I had rounds on the CA, flats on the Vintage Series and could maintian a similar tone shape with the two. I shoulda kept her, but the Lakland I stumbled on a few weeks later stole my heart. So, when a buddy offered to trade his Geddy Lee for my California, and I didn't have a Jazz bass at all, I opted for the trade. I shoulda kept the California, I'm such a P bass guy...
The first MIM versions were very similar except the fret work was a lot more sloppy and the rosewood boards had a much more open grain to the wood. Then they added active electronics and discontinued the passive versions.
