Designed for the versatility of today’s progressive music, the Martin GP (also know ans Grand Performance) has the depth and width of a “small jumbo,” as they are called by other guitar makers. It provides the punch of a 000, the projection of an OM, and nearly the same power and bass of a Dreadnought. Add in the cutaway of a GPC, and you have a Swiss army knife to handle any music called for at your next gig or recording session.
