You are looking at a Martin OM-18 Authentic 1933 Acoustic Guitar, serial number 1672738. This is the actual guitar you will receive should you decide to purchase.

All of the Martin Authentics in the Marquis Collection are based on existing vintage Martin instruments that have been selected for their superb tonal qualities and striking vintage aesthetics. These Authentic instruments are all crafted in the same manner as the originals to accurately replicate the tone, feel and look of an actual vintage instrument. Each vintage instrument has been thoroughly measured and X-rayed to ensure the utmost accuracy. Taking you back to the Golden Era of C.F. Martin & Co., these Martin Authentics utilize hide glue adhesive throughout and employ painstaking, historically-accurate detailing that is unique to the specific vintage instrument that is being replicated. These instruments are truly exquisite, and have been made with the discerning player and vintage-enthusiast in mind.

This one in particular is based off of a vintage 1933 OM-18, graced with era-correct OM-18 Authentic-style appointments, down to the Authentic 1933 neck barrel and heel.

The OM-18 Authentic 1933 Acoustic features a 000-14 Fret body crafted from a classic tonewood combination, solid Adirondack spruce with an authentic bracing pattern for the soundboard complemented by solid genuine mahogany back and sides to produce that coveted voice reminiscent of the original. The vintage style finish is the icing on the cake, further catering to the OM-18 Authentic 1933's old school Martin vibe. The neck is also carved from solid genuine mahogany into a period-correct profile and houses a 20-fret ebony fingerboard with old style 18 inlays.

One aspect that truly stands out on OM-18 Authentic 1933 is its visual simplicity. The OM-18 doesn't beat around the bush with appointments that are overly extravagant, it gets straight to the point by doing what this guitar was made to do-- and that is to deliver that genuine Martin tone and feel that guitarists have grown fond of over the years.

The OM-18 Authentic 1933 Acoustic Guitar comes delivered inside of a 533V Harptone style hardshell case to provide this instrument with superior protection.
