I keep two active basses - an Ibanez SR500 (2009½ model without the Mid Switch) and a 2010 MIM Deluxe Fender Jazz.
I find them to be both very closely interchangeable in sound and voice with just some subtle aural differences in sustain, with that value going to the Fender. The necks of course - are different as is the string spacing, weight, shape and fit - but none of that is a negative: just different.
What I find I like most about either/both of them is the broader pallet of tones and vocal qualities with the active circuits. I don't care if there are detractors, they just sound good and can pump or diminish frequencies as one sees fit for pretty much any venue or musical style.
Many times I can just grab either bass and a combo amp and leave the pedal train at home; they are that able to compensate for EQ and boost all by themselves.
Your experience with your Ibanez may have caused you some second-guessing and thoughts about that brand, but frankly they are a sweet guitar once you cross the SR500 threshold.
On my Fender Deluxe I immediately put the Elixir Nanos with the coated string since I like them so much on the SR500. I know there's a lot of badmouth about them for the kitty fur that develops - but they play good, sound super mellow and last forever.
The 'fur' that develops isn't any big deal nor is it something to worry about as it doesn't affect their sound at all. Enough about strings.
If you consider the Fender Deluxe Jazz I don't think you'll be disappointed at all. It's flashy in black and tort with chrome hubcaps and it's a very versatile tool that will fill many desires and needs for years to come as it can fit any style and voicing for any music. It's easy on batteries - with classic lines that are easy on the eyes and easy on the bank account you can certainly do a LOT worse.
OTOH: as much as I love both the iconic design and general acceptability of all things Fenderesque, the Jaguar didn't do 'it' for me as I found it to not be what it's purported to be. It found it was finicky and hard to dial in and generally I dislike all the knobs and slider/roller switch thingys.
I also bought the Squier VM-Jaguar, and although it isn't active, it sure can find places to sing that will be able to fit into any musical style given that one finds the correct strings for it.
I kept the purported 'Fender 7250 NPS' strings on it, but being as they are MII, they aren't really what they are rumored. They are NOT D'A strings made for Fender. They are NOT Fender 7250s either. What they
are is something much better. I have a set of GHSs in the wings for this bass and they may get put on sooner than later.
What my story boils down to is that there are a lot of orphaned basses out there, the Deluxe Jazz and even the VM-Jag, that respond very well to just a string change. The only time I am in the market for new p'ups and hardware is when I am building a bass from scratch.
I tend to buy what I like and just keep it that way.
