1993 Martin HD-28 Prototype Unproduced Dreadnought Acoustic Guitar, Maple & Cherry


+ shipping

Up for sale, a 1993 Martin HD-28 prototype in near mint, 100% original condition and in perfect working order. An iteration of the HD-28 which never made it to production, this one-off HD-28 prototype features a Sitka Spruce top framed by herringbone binding, with figured solid cherry back and sides, a satin-finished maple neck, and a roasted maple fingerboard.

Unique both visually and sonically, this HD-28 yields incredible definition and treble snap. The guitar responds as a square shoulder dreadnought should with muscle and ample projection, yet with a brightness and dynamic immediacy attributable to the tonewoods utilized in this prototype. Also a better fingerpicking guitar than many dreadnoughts, this Martin is smooth and detailed in every register with a pillowy warmth when played softly. The guitar weighs 4lbs 4oz, professionally setup here at Mike & Mike's Guitar Bar with fresh 12-54 phosphor bronze strings, easy-playing action, and accurate intonation.

The maple neck has a slender C profile carve with modest shoulder and lightly rolled fretboard edges, measuring .830" deep at the 1st fret and .890" at the 9th. The roasted maple fretboard features original perfect frets, and notes ring out clearly up the 25.4" scale. The nut measures a full 1 11/16" in width, and the headstock features a cherry headstock overlay and flawless Martin gold script logo. The Schaller-made and Martin-branded tuning machines have gleaming chrome plating and function smoothly.

Identifying this guitar as a prototype, "Custom" is stamped on the heel block above the serial number, and a perfect, unfaded Martin label is visible through the soundhole reading, "Production Prototype, This Instrument Is Not For Sale."

The bridge is carved from cherry, and the original saddle has plenty of height. The Sitka Spruce top is framed by Pre-War-style herringbone binding, with a touch of bookmatched bearclaw figuring on the lower bout on top. The body is finished in high gloss nitro lacquer, highlighting the broad quilt figuring and dynamic grain patterns of the cherry back and sides. The satin finish on the neck profile is flawless, and there's a touch of spalting in the maple, particularly on the heel. Save for a few light pick scuffs across the guard, the guitar is stunningly kept and virtually unplayed.

The original black molded Martin hardshell case is included.
