I recently purchased this jazz bass from rondomusic,

SX Ursa 2 MN Red Ash Bass Guitar at RondoMusic.com

and was looking for suggestions for upgrades.

I was going to put in a badass bridge and fender 60s pickups as well as a preamp but am unsure of which to get.

I'm looking to get a classic jazz bass sound out of this bass, reminiscent of 60s and 70s jazzes, very crispy, hot I guess?

If anyone could offer some input on different components I would really appreciate it.
