Got one. Great bass. Feels like a Fender with a really nice neck. Looks cool, too.
I prefer mine passive, but that's the way I am. There can be a grounding buzz, but this was literally a ten minute fix in my case. Sounds good, but there is no blend knob and only a single volume. I think the Jag has a very workable set of controls and a wide variety of tones, but a jass bass guy might miss the dual volumes.
This bass is on my "highly recommended" list. I don't like the price of them new, but again, that's the way I am.
EDIT: I've never noticed any neck dive on mine. My jazz bass dives a little though, and I've got a P that dives a little too (the body is ridiculously light), and I'm not sensitive too sensitive to this.
