I got this case for an offset Telecaster. It's a perfect fit. I can only assume it will also be a perfect fit for Jazzmasters and Jaguars.
The quality is good. Not anywhere near sturdy enough to send as cargo on a plane but more than adequate for transport in the back of a van or similar.
The handle isn't the most comfortable but then again, most guitar cases have this problem. For everyday situations like going to rehearsals I would rather use a gig bag than carry this case around.
But it's a good quality case that does what it's supposed to do. And if you've got an offset Fender there really aren't many other suitable options out there.
