Martin OM-28 Standard Series 2025 – 1933 Ambertone w/Case

The Martin OM-28 Standard Series 2025 in 1933 Ambertone combines one of Martin's most respected acoustic guitar designs with the tonewoods, vintage-inspired bracing, and refined playability of the refreshed Standard Series. With a solid spruce top, solid East Indian rosewood back and sides, Golden Era scalloped bracing, and a comfortable GE Modified Low Oval neck, the OM-28 delivers the balanced response, projection, clarity, and rich overtones that have made the Orchestra Model a favorite among serious players.

This particular Martin OM-28 Ambertone is brand new and has received a complete professional setup by Metz Music, so it is playing at its absolute best and is ready to go right out of the box.

The 1933 Ambertone gloss finish gives this OM-28 a distinctive vintage-inspired appearance while allowing the classic Style 28 appointments to stand out beautifully. Bold herringbone trim, antique white binding, an ebony fingerboard and bridge, abalone fingerboard inlays, and nickel open-gear tuners complete the look.

A Modern Martin OM-28 With Vintage-Inspired Tone

The Martin OM-28 is one of the most versatile instruments in the Martin lineup. Its 000-14 fret Orchestra body provides a comfortable playing experience while retaining enough body depth and resonance for a full, authoritative acoustic voice.

The solid spruce top works with the solid East Indian rosewood back and sides to produce a powerful yet balanced tonal spectrum, with clear trebles, rich overtones, and a deep, controlled bass response.

The 25.4" long scale contributes additional string tension, projection, clarity, and sustain, making the OM-28 particularly well suited to fingerstyle playing, flatpicking, singer-songwriter work, recording, and full-band performance.

2025 Standard Series Updates

Martin refreshed the Standard Series for 2025 with several meaningful design and construction updates. The OM-28 incorporates Golden Era (GE) scalloped bracing, a bracing approach inspired by Martin's vintage instruments and designed to provide enhanced resonance, sustain, and vintage-inspired tonal character.

The neck features Martin's Golden Era Modified Low Oval profile with High-Performance Taper, giving the OM-28 a comfortable and contemporary feel while retaining the familiar character players expect from a Martin neck.

The updated Standard Series design also includes a refined bridge and heel, a thinner fingerboard, and other detail changes intended to improve both playability and aesthetics.

Solid Spruce & East Indian Rosewood Construction

At the heart of this OM-28 is a solid spruce top paired with solid East Indian rosewood back and sides.

This classic tonewood combination is prized for its combination of projection, harmonic complexity, warmth, clarity, and dynamic range. The rosewood construction gives the OM-28 plenty of depth and richness while the spruce top provides articulation and headroom.

The result is an acoustic guitar that responds beautifully to both a light touch and a more aggressive attack.
