Martin OM Mikael Akerfeldt Signature Acoustic Guitar

The Martin OM Mikael Åkerfeldt Signature Acoustic Guitar is a bold collaboration between Martin and the progressive metal icon, Mikael Åkerfeldt of Opeth. This limited-edition 000-14 fret guitar brings a darker, heavier aesthetic to the classic Martin OM body shape, blending traditional craftsmanship with modern playability. Featuring a torrefied spruce top and a striking three-piece back of Guatemalan rosewood with an East Indian rosewood wedge, it delivers a rich, vintage warmth with exceptional clarity and resonance. Designed for players who appreciate the feel of an electric guitar, it is the first traditional Martin acoustic to feature the Low Profile Velocity neck, offering sleek, fast playability and a full 25.4” scale length.

Every detail of the OM Mikael Åkerfeldt has been thoughtfully crafted to reflect Mikael’s unique style and vision. The ebony fingerboard is inlaid with black mother-of-pearl Roman numerals, adding a shadowy, personal touch. The guitar’s VTS-treated spruce top and Golden Era scalloped X-bracing enhance its responsiveness and tonal complexity, while black Liquidmetal® bridge pins contribute to sustain and clarity. European flamed maple binding and bold herringbone trim complete this striking instrument’s look, making it as visually impressive as it is sonically inspiring.

Limited to only 74 guitars worldwide, each OM Mikael Åkerfeldt comes with a custom stainless-steel label and a Harptone case, making it a highly collectible piece for fans of both Martin and Mikael Åkerfeldt. Whether you’re a seasoned player seeking a high-performance acoustic or a collector looking for something truly special, this guitar offers a unique blend of tradition, innovation, and metal-inspired attitude.

Low Profile Velocity Neck

The OM Mikael Åkerfeldt features Martin’s innovative Low Profile Velocity neck, designed to offer the fast, comfortable feel of an electric guitar. With a high-performance taper and a full 25.4” scale length, this neck allows for effortless playability and ample room for expressive playing styles.

Torrefied Spruce Top with VTS Treatment

The torrefied spruce top is enhanced with Martin’s VTS (Vintage Tone System) treatment, which accelerates the ageing process of the wood. This results in a warm, vintage tone with excellent responsiveness and projection, perfect for both fingerstyle and strumming techniques.

Guatemalan and East Indian Rosewood Back

The dramatic three-piece back combines Guatemalan rosewood wings with an East Indian rosewood wedge, providing a rich, complex tonal palette. This combination offers deep lows, sparkling highs, and a balanced midrange that complements the spruce top beautifully.

Distinctive Aesthetic Details

From the ebony fingerboard inlaid with black mother-of-pearl Roman numerals to the European flamed maple binding and bold herringbone trim, every visual element of this guitar reflects Mikael Åkerfeldt’s dark, progressive metal sensibility. Black Liquidmetal® bridge pins add a modern touch while enhancing sustain and clarity.
