New model from Martin. The Road Series are made in Mexico. Seems like a good entry level all solid model to win over players who prefer the grand auditorium shape.
I briefly owned a DRSGT (the dread shape in this series) and I think this one has more or less the same appointments. Seems like the sipo neck has been replaced by “select hardwood” on the GPC. And the bracing pattern is different. DRSGT has the A frame while GPCRSGT has Hybrid X. Not sure how this affects the tone since wood is organic and each guitar is different even if they are the exact same model.
