Travel guitars that I’ve seen don’t look much like a regular acoustic guitar. The ones I’ve seen tend to be narrow, stick-like instruments. I’m not a musician, but it seems to me that the smaller body would negatively impact the sound produced by the guitar. I don’t know what the shortcomings of the Voyage-Air travel guitars might be, but they certainly have a normal-sized body. Their guitars have necks that fold down so that they pack into a backpack that’s easier to travel with than a full-sized guitar case would be. (The bag might even work as your carry-on so that you don’t have to worry what’s happening to your guitar in the cargo hold.) Voyage-Air has a variety of models, like the Transit Series VAOM-02 Orchestra Model acoustic shown here. The VAOM-02 has a full 25.5″ scale length and 1 3/4″ neck and is made from “toughest engineered tonewoods”. It’s $399.00, and the new Transit Bag carry case is included. Voyage-Air also offers dreadnoughts, left-handed guitars, and electric guitars, all with foldable necks.
