I own a Martin 000-15 and used it as my primary axe to record my debut album. I also play it out live a lot and get compliments on my tone. It has a more "woody" and "Americana" tone, as opposed to the Taylor, and well balanced for fingerstyle. If you want to listen to audio clips of the Martin 000-15 you can check out
