The Traveler Ultra Light Acoustic Electric Travel Guitar is basically a solid maple bat with strings that can stand up to rough and tumble travel. Plug it into an amp or mini-amp with headphones (sold separately), and you'll hear a sweet sound. I've taken mine overseas and camping throughout the U.S. and never had to worry that it was going to be damaged. I'd use it as a weapon if attacked and worry about the other guy as it twangs against his head.
Because the Traveler Ultralight tuning pegs are built into the body, some owners say changing the strings can be a bit of a challenge the first time through. I haven't changed mine yet, so I really can't comment. What I can tell you is the tuners are well constructed and keep the strings in tune for a long time.
