Well, my advice is that if you're going to get one. Spend the money on a good one.
I bought, what I thought was going to be something usable, off of ebay...
Boy was that a big mistake!! It didn't cost me much (2 travel guitars for 20 dollars) but what I got was about as laughable as a streaking clown.
These "Toy guitars" were completely unplayable.
The stock strings that came with it may as well have been thread. And once they were removed/replaced that led to the discovery of the jury-rigged bridge.
The bridge on the guitar was not affixed to it...so once you put on good strings you had to adjust the bridge to get it to intonate right. And then it wouldn't last because after playing it for 2 minutes, the bridge would have moved. The only way to get things rolling for more than 5 minutes was to get the bridge placed right for correct intonation...and then crazy glue the sucker in place.
The tone of the junk "travel guitar" was that of any toy guitar you pick up at the dollar store. It sounded more like a cheap ukelele than a guitar of any sort.
The only difference being that it was made of plywood instead of real guitar wood.
I've heard that Taylor makes a quality travel guitar that has a good sound, but I haven't experienced it.
