Martin's X Series, their most affordable series, utilizes a high-pressure laminate back and sides to create an inexpensive, rough-and-ready instrument for the player who seeks beauty, durability and tone while staying within a budget. The resilient HPL (high pressure laminate) bodies are made to last and Martin's Stratabond necks, constructed in laminated layers, are so strong you'd need a diamond cutter to cut them. Fingerboards are made of black Richlite. Tops are crafted from solid Sitka spruce, a sleek jet black HPL textured finish, a spruce pattern HPL textured finish, or a handsome Hawaiian koa HPL pattern textured finish.
