I have a 5. They have been getting less than stellar reviews lately, although I have to say I love mine. I got my hands on an alleged NAMM demo, so I practically stole it. Plus, it looks like Roger Sadowsky broke into the factory and added his personal touches to it visually.
Some negativity I have heard about it:
-Chunky neck: This is true, the neck is thicker and wider than most 5's. Not a problem for me, although I had always associated a Jazz bass with a narrow neck. I think it's 1.85" or 1.9" at the nut, where a good deal of 5's are 1.75"
-Bad finishing around the frets: check the fretboard thoroughly before you buy. This was the case with mine. Since I paid such a low price for a practically new bass, I didn't care in this instance.
-The electronics/preamp: No complaints with mine so far, although I have heard of 4-string Jazz Bass 24 models whose preamps have died. I really hope Fender took care of this, and if not I imagine we'll be hearing about it soon enough...
-The sound: here's where this bass could fall short, mainly because many people will expect it to sound like something it's not (a vintage/passive Jazz). You can switch from active to passive, although you lose the use of the tone controls if you do so. No issues with the B on mine, thunder aplenty. I've played active basses for some time now, and passive models tend to leave me looking for the Nitrous switch, so it's not an issue here.
If you don't already own a jazz, this one could well ruin your opinion of those 'other' models if you appreciate it for what it is, and you're willing to overlook it for what it's not.
