I am getting an SX 4 string P/J bass. Keeping in mind it is only a 120 dollar bass (so no Aero pickups!), what pickups would be a good upgrade. This bass would be mainly for (classic style) rock covers. Probably get a schaller bridge (can't bring myself to put something on the bass that says "ass") If this has already been debated elsewhere, just post the link to the thread. I didn't have any luck searching.
