Well, I´ve only ever tried one, and that was a disappointment.
Well made, typical CIJ quality, very good looking.
Terrible setup, but that´s not the fault of the bass.
Lots of sounds, but none of them inspired me. The electronics were very noisy, loud hissing and humming no matter what I did - active and passive mode, with one and both pickups, with treble on or off, different amps and leads...
Personally, I´d take any standard Jazz over the Jag (even without the hiss).
BTW, it´s still in the shop and has been for months, so others obviously feel the same about it...
