Aged Appearance and Tonality

The Martin OM-18 Authentic 1933 is an exquisite acoustic guitar is based on a 1933 OM-18 on loan from Fred Oster of Vintage Instruments. Built from genuine mahogany and topped with solid Adirondack spruce, the OM-18 Authentic 1933 gives you a warm, lively tone framed by a crisp, clear character with incredible response and massive headroom. On top of that, this remarkable acoustic guitar was treated with Martin's Vintage Tone System (VTS), so it convincingly evokes the aged appearance and tonality of the 1933 original. Topped off with period-correct appointments, including an Authentic 1933 neck barrel and heel, the Martin OM-18 Authentic 1933 acoustic guitar is bound to cause some commotion here at Sweetwater!

Carefully-selected tonewood combination for phenomenal tone

This Martin OM-18 Authentic 1933 acoustic guitar is built from highly-prized tonewoods. Full of warmth and liveliness, you'll love the bright, responsive sound of this OM-18's genuine mahogany back and sides. On top of that, this OM-18 is topped with solid Adirondack spruce, adding crisp and clear overtones to an already exquisite tone. Widely used on pre-war and vintage instruments, the clarity of Adirondack is unrivaled. Make no mistake, you'll be a believer after a single strum!

Vintage Tone System (VTS) for aged appearance and tonality

Martin's unique torrefaction process, called Vintage Tone System (VTS), allows their guitar builders to age the tops and bracing of their instruments to specific time periods, bringing out the character that an instrument from that year would likely possess. On top of that, Martin's Vintage Gloss Finish (which is applied by hand) also adds the warm glow appearance that you'd expect from a vintage acoustic guitar. In short, Martin's VTS provides you with the historic tones and visual aesthetics that were previously reserved for vintage instruments.

Authentic 1933 barrel and heel neck feels incredible

Martin's barrel and heel necks are remarkably thick, almost to the point that it's hard to wrap your hands around them. That being said, the longer you play them, the better they feel. In fact, you'll eventually reach that pivotal moment when this becomes your favorite neck! Many players find that when they become accustomed to barrel and heel necks, they quickly realize that these necks allow them to anchor the palm of their hand in more ways than a thinner neck. On top of that, the resonance and sustain that these necks allow is the stuff of legends!

The Orchestra Model - Martin's first modern guitar

In 1929, a banjo player named Perry Bechtel approached C. F. Martin & Company requesting that they build a new guitar model with a longer, narrower neck. Martin responded by building their first guitar to have 14 frets clear of its body, rather than 12 as in their previous models. These guitars had a 25.4" scale length, a solid, non-slotted headstock, and a glued-on pickguard. These new guitars, named the "Orchestra Model," marked a turning point for Martin, as they discontinued production of 12-fret guitars almost overnight. By 1934, Martin's OM models had morphed into the now-familiar 000 models.
