I currently own a Squier Affinity Jazz bass, but after playing a lot more lately I think its time to spend some money on a new bass, and still hold onto my Squier. I'm looking to spend 400-600$ on a used bass, but I am not sure what I should be looking for. Since I enjoy playing my squier jazz I am interested in upgrading to a nicer MIM Fender Jazz. However I am also interested in maybe switching it up and getting something a little different sounding than the Jazz I already own. I've been pretty interested in some Ibanez, Schecter, Aria, and Bacchus guitars. Any recommendations? I like having a thin thin Jazz neck, and versatility in what kinds of music I play.
