The X Series guitars are constructed with a combination of highly compressed wood fibers (highpressure laminate, abbreviated as HPL) and traditional tonewoods. Martin has found HPL to be an extremely durable and workable material.
Martin have crafted ways to build traditional Martin shapes with HPL that yield incredibly long-lasting, affordable guitars. Most importantly, they have managed to build them so they possess the “famous” Martin sound and playability found in their more expensive guitars.
The DX1 features a basic dreadnought style.
