Greg Olwell demos the Martin GPC-13E Grand Efficiency Cutaway acoustic-electric guitar, a brand-new addition to the storied maker’s Road Series. States Olwell, “The GPC-13E is an easy option for gamers needing a dependable, handsome guitar that sounds good acoustically and plugged in. It would also be excellent for gamers who like the noise of a dreadnought’s accentuated bass and treble but want a guitar with more playing comfort. The GPC-13E is the type of roadway warrior guitar that you might rely on for simply about any gig that might come your way.”
