Martin D-28

The Martin D-28 is a dreadnought-style acoustic guitar made by C. F. Martin & Company of Nazareth, Pennsylvania.

Martin D-28

1931–present

Square-shoulder dreadnought

Current models[edit]

Starting with the 2017 D-28's Martin has switched to forward shifted X-bracing, a revised neck pattern termed High Performance Taper with Modified Low Oval profile with 1-3/4” ebony fret board width at the bone nut, 2-1/8” at the 12th fret. The previous black pickguard is now faux tortoise shell and the former enclosed tuning machines are now open gear. Aging toner is applied to the Sitka Spruce tops before application of the nitrocellulose lacquer finish.


The modern D-28 standard series is made of several high quality tone woods, including solid Sitka Spruce tops, Indian rosewood back and sides, mahogany neck, ebony fret board, ebony bridge, and maple bridge plate. It uses the classic non scalloped X bracing pattern prior to 2017 pioneered by Martin, along with an ebony bridge and fret board. Much of the construction is still done by hand although in recent years Martin has adopted computer controlled CNC machines to fashion the guitar's neck, and employs automated buffing and polishing machines, while maintaining the overall quality of the finished product.[5] As of 2020, a base model has a list price of $3,599 U.S. Martin dealers usually offer discounts off the list prices. Older models made in the 1940s, 1950s and pre-1969 D-28s can command far greater prices.[6]

HD-28: Has scalloped braces, said to give the guitar a more "open" sound than a D-28. Also features the herringbone (or "pre-war") top border and a zigzag, or "zipper" backstrip.[8]

HD-28V: This variation resembles the original pre-war model and features both chrome butter-bean tuners and herringbone bindings around the aged-toned top. The X of its scalloped bracing pattern is shifted forward (toward the sound hole) by approximately one inch, making the lower bout top vibrate more freely/responsive, and resulting in a very potent and bass-rich guitar.

D28E: A very limited run version of the D-28 with special pickups placed at the end of the fretboard and near the bridge. While not generally well received, it is considered a collectors item.

D12-28: A 12-string version, otherwise the same as its brother the D-28.
