In this [article](http://www.martinguitar.com/players/martin-ambassadors.html) from Martin Guitar's official site, you can see that Jake is a "Featured Martin Ambassador" who's preferred guitar is a 00-15M.
It's a Martin, what else is there to say? Mine's seen a lot of wear & tear but still gets it done. Sounds nice with phosphor bronze strings I might add.
