I really perfer a mixture of both , i'd rather have the CV neck , bridge and guard on the VM body and pickups.
There both great basses, i perfer gloss necks tho so i would get the CV
If you get a VM jazz, id gladly trade necks for my CV neck. Seriously. Thats how I want to do my bass. CV body, VM neck. Dont know why, I just love the bound and blocked neck on a white body.
Anyway, I own a Classic Vibe 60's jazz, and absolutely love it. I sold my MIM Fender jazz to get this one. The bridge is good and solid, and is very comparable in attack/sustain to the badass II I had on my other jazz. The neck is butter, and the over quality is better than some MIM jazzes ive owned.
Ive played a VM quite a few times, and its very comparable quality to the CV. The body is awesome, the neck is well built, and the overall build quality is awesome. The pickups are amazing too. Very much a little brother to the quarter pounder.
So theres give and take on both. If you like swapping bridges out, and dont really care about pickups, get the VM. If you like the bridge on the CV and want to do other mods, the CV is awesome. Thats the only downside to the CV i can really think of, is the non standard bridge hole pattern.
