With portable tuners, recorders, and the like, it's pretty easy to take your whole music rig mobile—but what about that guitar, in an enormous case that makes it look like you might be carrying a 30s-gangster semi-automatic rifle? Stewart Guitars specializes in guitars with detachable necks; they fold neatly into a suitcase, the instrumental equivalent of an extreme contortionist. They've just unveiled a cheaper import version (US$650 and up), so you can pick one up, toss in your keychain tuner, and practice in hotel rooms.
