Hello everybody!
Ok, so right now I'm in between my freshman and sophomore years of college. I've recently acquired a good-paying the job for the summer and I plan to buy a really nice bass right before I go back to school. I've gone back and forth between modding a budget bass or just buying a bass that is good enough stock to leave alone, and I've decided I would rather buy a "lifer" than a hot-rodded cheap bass.
By lifer I mean a bass that is solid enough that it'll undoubtedly last me a lifetime, and I'll never even think about wanting to get rid of it. I know all of that stuff is subjective, but what it comes down to is I want to drop somewhere between $1000 and $1500 on this instrument. I know price isn't necessarily an indication of quality, but I want this to be a professional-quality instrument, not just a good bang-for-the-buck. Maybe I should include that I gig regularly and record semi-regularly, so any instrument I acquire will be put to use and will definitely be put through its paces!
So far I've been considering:
A used Rickenbacker 4003 (A lot of times they're closer to $1600 but I could bend my own rules for this one

)
An American Jazz Bass (American professional or American standard- I've played both and can't find much of a difference playing and sound-wise)
A Fender P bass (Probably the Classic 50s, which is actually below my potential price point, but I can't imagine a P-bass being much better! OOH- Except maybe the Mike Dirnt Roadworn!!) btw- If I go for this one I may add a second 15" cabinet to my rig with the money I'd save

A used Musicman Stingray (Nuff said)
Lastly, something by Lakland (I haven't done too much research into their stuff, but I know they make some awesome instruments that can be had for around my price-point)
I've seen a lot of these type of threads, but this isn't as much a question of what should I buy, but what are some really nice basses to check out that can be had for $1000-$1500?
My requirements/preferences:
I only want to buy one bass
No modifications NEEDED to make it a solid bass
I prefer 4 strings
I've generally stuck to passive instruments but not by rule
I would like something American (but that's not necessarily a requirement)
