Martin Grand Performance GP42-15 - Sweetwater at Winter NAMM 2015

See the GP42-15 here: http://www.sweetwater.com/store/detai... The Grand Performance GP42-15 acoustic-electric guitar from Martin is a spectacular stage performer. Built from highly-flamed Hawaiian koa, and topped with an aged torrefied European spruce soundboard, these guitars deliver plenty of clean tone and rich low end framed by crisp and clear overtones that work well for all playing styles.
