The Active Jazz is basically a Standard Jazz with upgraded electronics. The body and neck are identical to the standard jazz. That being said, it is a great bass for the money. The preamp is very usable and the Noiseless pickups are just that....Noiseless! I had a sunburst model, but I really like how the Vintage White model looks! The Mexican plant has really been putting out some great instruments, and I would not hesitate in a minute to buy one.
Not actually, there slight differences.
First, the Deluxe body
It has a side mount jack and a battery box routed into the back of the body and the body is slightly thicker than a standard MIM Jazz to accommodate these differences. This allows you four knobs on the control plate and simple access to a battery if you are using active controls. In spite of this difference a guard cut for neck and bridge pickups from a Standard MIM J will fit although it may need a little drill and fill to get your screw holes worked out just right. The standard control plate is a direct replacement for a Deluxe control plate although you may occasionally need to also fill and drill plate screw holes to get the gap just right.
Second, the MIM Deluxe jazz has always had the standard J pickup routes, even when the MIM standards were sporting 2 pickups of the same size. At least all the older Deluxe J's from that era I've had were cut that way.
Last, the neck pickup/control cavity route is larger than a standard to accommodate the preamp board, an additional pot and the increased wiring bulk for the preamp.
The Deluxe bodies I've stripped were constructed with a series of reddish looking planks glued up into a slab then sandwiched between two pieces of thin white wood. They work well for a transparent center sunburst finishes because there's no seam showing on top, giving the impression it's a single piece of wood.
There are also differences in the necks.
First, all Deluxe J necks have had Pau Ferro boards on them as long as they've been in production. It was only recently the Standard boards were replaced with PF.
Second, the neck edges, more specifically the fret ends, show a much higher degree of finish than do the MIM Standard necks.
It was the extra knob on top and the nicer fret dressing and PF board that first got me looking at Deluxe J's.
