I just picked one up recently. I think I got lucky and got a good one.....because the low B is solid and the build quality is as good as MIA.
You did get lucky.
One of my students did not get so lucky with his Fender MIM Jazz 5, and the B is pretty bad.
This is one model I would never purchase sight-unseen, and not before a thorough workout/trial period with some kind of return policy firmly in place.
