The active bass that I have is a 99 or 2000 Ibanez SR 485 5 string bass guitar. I love the playability of this bass. I got it used for a good price and I am enjoying it. yet, the pickups are kinda of weak especially when I play the D and G. Plus a lot of times when I want to cut down on the mids depending on the tune it has that Fieldy kind of sound which seems to haunt a lot of 5 string Ibby's from that era. Is it the wood, pre-amp, pickups or what? I used to run my Fender MIM J bass on the same amp setting and didn't get that Fieldy thing. Anyway would upgrading the pups help, or do I need to upgrade the pre-amp too? My other bass is a passive Ibanez GSR 200. It has a simple PJ configuration. I want to get it a bit hotter. The P has some thump, but the J pup doesn't have the growl I want. Would could you guys suggest basslines, seymour duncan. I don't know much about the different after market companies. The only thing I can say is that I am not a fan of those EMG HZ soap bars. Please educate me.
