It's been almost 35 years since I last owned and regularly played a passive Jazz bass, but from memory the Corvette is not even in the same ballpark. But the passage of time means I really can't speak for any direct comparison to a passive Jazz bass, but hopefully this will help:
There are two pickup types available on the Corvette - the passive 'Dynamic Correction' or 'MEC Silver', and the active EMG-type also known as 'MEC Gold', which have a preamp/buffer built into each pickup - even in passive mode the pickups themselves are still active. The 'silver' and 'gold' refer to the paint colour used for the logotype on the pickup housings:

Mine has the active 'MEC Gold' type, and to me this bass is not really anything like what I remember of my passive Jazz basses. The bridge pickup is about an inch closer to the bridge than a '60s Jazz bridge pickup, perhaps 3/4" closer than a '70s Jazz. The neck pickup is well over an inch closer to the bridge than the neck pickup of a Jazz. In theory this should make the overall tones brighter and a little thinner, but with the active pickups and preamp this is not the case. The neck pickup is thick and resonant yet still preserves some good transients. The bridge pickup is very clear and punchy if you play back there but still delivers plenty of bottom end 'goo' if you play over the fingerboard. The on-board preamp is very powerful and a little goes a long way, especially on the bass boost.
