Anything before 2008, if you want to play them that is. In 2008, Fender really started getting their act together in terms of quality control and design improvements. The new Fenders since 2008 are, IMO, much better instruments than anything made before then (even the old pre-CBS basses which were still somewhere between ho-hum and crappy in terms of build quality, wood quality and sound).
The new basses, tho, are pretty well-made instruments...

I love my new amer std 5er P I played ALOT of basses and was really impressed with the way Fender is stepping it up with they're new american standard line, very good quality/feel and great tone. This is what I always imagined a Fender to be. I could have bought any bass, but this simple P is it for me
