I have a warwick corvette passive that plays wonderfully, but it's passive pickups can only go so far, so i figure it's time for an update. So i was thinkin either basslines pickups and preamp or bartolini pickups and preamp. which would be better? what characteristics do each have? pros? cons? I play alternative, funk, slap stuff, and other stuff along those lines if that makes any difference in terms of choice. Thanks!
