The Modern Deluxe Series combines Martin’s legacy of old world craftsmanship with some impressive contemporary features. This guitar has scalloped, forward-shifted x-bracing and the body is constructed using natural protein glue, both features Martin used during the 1930s, the era when the modern flattop guitar was created and refined. The modern features include a carbon fiber bridge-plate, which is light and stiff and helps increase volume and sustain; a Vintage Tone System (VTS) spruce top; long wearing EVO frets; and an new asymmetrical neck shape that gives you maximum comfort up and down the fingerboard.
