C.F. Martin & Co. has announced a unique collaboration with progressive metal legend Mikael Åkerfeldt of Opeth, unveiling the striking Martin OM Mikael Åkerfeldt Signature Acoustic Guitar. This highly collectible, limited-edition instrument merges Martin’s iconic acoustic heritage with the dark, sophisticated aesthetic of one of modern metal’s most revered guitarists.
Martin OM Mikael Åkerfeldt
Limited to a worldwide production run of only 74 guitars, this 000-14 fret model offers a unique proposition for guitarists: the rich, complex tone of a classic Martin OM body combined with the sleek, high-speed playability of an electric guitar. The collaboration marks the first time a traditional Martin acoustic has been equipped with the innovative Low Profile Velocity neck, a design choice directly influenced by Åkerfeldt’s demanding playing style.
A Fusion of Metal Ethos and Acoustic Tradition
The OM Mikael Åkerfeldt signature model is a masterclass in visual and sonic design. Its sound is powered by a torrefied spruce top, treated with Martin’s Vintage Tone System (VTS) to produce the warm, mature character of a well-aged instrument right out of the box. This is paired with a stunning three-piece back featuring wings of Guatemalan rosewood and a central wedge of East Indian rosewood, delivering a powerful tonal foundation with deep lows, articulate mids, and sparkling clarity.
Reflecting Åkerfeldt’s unique artistic vision, the guitar features distinctive aesthetic details. The ebony fingerboard is adorned with shadowy black mother-of-pearl Roman numeral inlays, a personal touch that sets it apart. The instrument is framed by European flamed maple binding and a bold herringbone trim, creating a look that is both elegant and imposing.

Unparalleled Playability for the Modern Player
A key feature of the OM Mikael Åkerfeldt is its Low Profile Velocity neck. Engineered with a high-performance taper and a full 25.4” scale length, this neck profile is specifically designed to offer the fast, comfortable feel typically associated with electric guitars. This makes it an ideal instrument for players who transition between acoustic and electric, or for those who demand effortless speed and fluid playability for complex passages.
“This guitar has been thoughtfully crafted for players who appreciate both traditional acoustic sound and modern performance,” said a representative from Martin. “The collaboration with Mikael Åkerfeldt allowed us to push boundaries and create an instrument that is as sonically inspiring as it is visually captivating.”
A Collector’s Piece with Premium Features
Every element of this limited-edition guitar has been carefully selected for performance and exclusivity. The Golden Era scalloped X-bracing enhances the top’s responsiveness and tonal complexity, while black Liquidmetal® bridge pins contribute to increased sustain and volume.
Each of the 74 guitars comes with a custom stainless-steel interior label and a premium Harptone case, solidifying its status as a must-have for serious collectors, Opeth fans, and discerning musicians alike.
