Traveler Guitar makes a variety of travel sized guitars, both electrics and acoustics. I liked the idea of an acoustic for the simplicity of not having to plug it in to practice. Plus, I simply prefer acoustic over electric sounds these days.
In the photo, I put the Traveler next to my Taylor for comparison. One thing I love about the Traveler is that it has a full scale, 25.5" neck. Even though it doesn't have a cutaway like the Taylor, I can more easily reach higher notes on the Traveler. You can't see it very well in the photo, but the tuners are on the end of the strings by the body of the guitar. It also has a pick-up, so I could plug in and use it as back-up guitar if the need arose. The Traveler's tone is decent, but with such a small body, the guitar lacks a depth of sound. It doesn't even compare to the Taylor, which has the most beautiful sound of any guitar I've owned, including a gorgeous Heritage 575 that I still play.
But I didn't buy the Travel for the tone. I bought it for portability. I'll be taking it to the UUMN conference in July, and it'll replace the guitar I currently use for teaching. And the Travel has one thing the Taylor doesn't: a strap on the end so you can hang it on a hook. Bonus points for cuteness.
