Description

The Custom Shop 000-28K 1921 brings the warmth, beauty, and vintage character of an early all-koa Martin to life with stunning detail. Its 000 12-fret body is crafted from highly figured koa, features a thin vintage gloss finish, and is accented with grained ivoroid binding, fine herringbone top inlay, and a faux tortoise under-finish pickguard. Traditional hide glue construction and VTS-treated Authentic scalloped Adirondack spruce X-bracing deliver exceptional responsiveness and resonance, while the long 25.4" scale length and wider 1 7/8" nut width offer a spacious, expressive feel. A slotted headstock, a pyramid ebony bridge, Golden Era diamond-and-square abalone inlays, and an Authentic 1921 neck shape complete the vintage-inspired design. 

Available only at Custom Shop Expert Dealers
