The new OM-1GT model is designed with Martin's legendary tone, craftsmanship and playability with extraordinary value. It features solid sapele spruce backs and sides, a solid Sitka spruce top and is polished to a high gloss. Tonally, the advanced "hybrid" scalloped X-bracing delivers a powerful punch - clear ringing treble and deep bass - unique to Martin's 1 Series guitars. The Martin OM-1GT Orchestra Model produces a tone that is brighter in the midrange, less deep in the bass and clear articulation in all positions.
