I bought this model last June and I love it! I have had a Guild classical that was given me by my Dad when I was 14 years old (that probably makes it an antique - but it still has a beautiful rich sound and although it's a little the worse for wear - having been dragged all over the place). I still love it. But it didn't have a built in pickup. And I wanted to go to steel strings for a change. I tried out a lot of guitars and the Martin 000-15S was the one I kept coming back to. It has a very lovely sound and a lot of resonance, too.
