I have the Mexican bass, which I really like. Plays great, sounds great etc. Walked into a local shop today and they are selling off a brand new Am Jazz 5 for $600. I didn't get much time with it as I was in a hurry, but the B string seemed to sustain better than on my Mexi bass. Anyone have experience with these two to comment on whether getting the American made bass (with graphite in the neck and strings through the body bridge) is worth a few hundred $$ after I sell off the Mexi J5? Thanks!
