Guitarists don't really have it easy when it comes to traveling, so Voyage-Air Guitar will probably be the best option if portability is a must-have quality.
Traveling on a plane with a guitar can be annoying. It costs more if it's extra luggage, it could break when thrown on the plane and you have to either take out all the strings or loosen them up to prevent the pressure from breaking them. The Voyage-Air Guitar eliminates all those problems because the neck is collapsible on all six strings, which shrinks down the size of the guitar greatly. The backpack that comes along with it adds to the convenience, with compartments for cables and the axe itself, which tucks neatly inside. This is definitely something any musician can use when he's touring worldwide.
