I gig here and there but mostly play just for fun. I've had a Fender Jazz Bass (Mexican) basically since I started playing as a teenager. I upgraded the pickups a while back because the stock ones buzzed and I wanted more of a "sublime" sound (I was a teen!). Now I'm wondering how a Deluxe Active Jazz Bass might differ from the above? How much of an upgrade, if at all, would this be? I've never played an active bass before, but get the impression they're significantly more popular. I'm not a mid-range freak, though. I see this bass in the $500-$600 range. If the above won't sound that different, I'm also consider a Dean Performer Series Acoustic Fretless bass, which is a little cheaper but really would only be used for messing around in my flat. Thanks for any helpful pointers! I don't recall the specific pickups I have in my Mexican J-Bass--I think they're single-coil basslines. I maxed out on highs and lows.
