Wife wants a guitar

If you can find a Fender DG series, its a great little guitar to learn on and is pretty inexpensive. You should get your wife to play around with guitars with different widths to the necks and see what she is comfortable with. I would also second the "set up" but only if she is actually going to play it. Let her play for a month or two first, then take it in to get "set up." Sure, it might only be $30-40, but I know too many people who wanted to learn, bought a guitar, played for a day or two and decided it "had to be set up right" only to have their desire to play fade with a new fad in the two or so days it took for a guy at a guitar shop to get to it. After she plays on it for a month or two and wears out the crappy strings it comes with, bring it in for the "set up." Itll get great new strings and sound like a much better guitar with an improved action. I've found that "new sound" keeps people's interest pretty well because they come back to playing and it sounds better than they remembered, making them think they have improved.
