What is a Martin "GP" Grand Performance SIZE ???

This body size combines the best of the Dreadnought Dsound with the best of the Orchestra Model OMcomfort!! The rich thunderous tones of the Dreadnought combine with the intricate well-balanced complex voice of the OM. This guitar body produces a combination of Traditional Martin Soundwith the VERY BALANCED Contemporary voice--one that shines with beautiful, clear, bell-like trebles. At the same time, you hear a sturdy bass that supplies just the right amount of power. The mid-range tones stand on their own, full and rich partners that give abundant life to many styles of flat-picked and finger-picked tunes!

In the first photo, the guitar on the left is the D Size; the guitar in the Center is the GP Size (Grand Performance); the guitar on the right is the OM/OOO Size.
