Went with a set of D'Addario Phosphor Bronze (Light), and boy was I ever reminded of how huge a difference strings make when it comes to a guitar like this one (or any really). Thing really sings now, and is way louder than it was before unplugged too which is great for when I don't feel like plugging in.
Anyway I think this particular model is discontinued (though they still make the AC375) but they are WELL worth grabbing whenever you see one at a great price.
Here's a quick flash-y pic or two, and I'm off to wear these strings down again...
