The Mario Beauregard Antoine Dufour Signature OM is the kind of instrument that exists at the meeting point of absolute lutherie mastery, modern fingerstyle composition, and uncompromising musical utility. Built by one of the great contemporary Canadian luthiers, this guitar reflects Mario Beauregard’s gift for refinement at every level, from voicing and response to ornamentation and player focused ergonomics. Beauregard’s work has long been admired for its balance of elegance, precision, and musical depth, and in this Antoine Dufour Signature OM, those qualities are placed in direct service of one of the most expressive acoustic players of the modern era.
Antoine Dufour’s music demands an extraordinary instrument. As a world renowned fingerstyle composer and performer, Dufour’s playing often moves beyond traditional guitar technique into a fully orchestral language, combining melody, harmony, percussion, altered tunings, harmonic textures, and wide dynamic shifts in a single performance. A guitar built for his world must be immediate, sensitive, balanced, stable, and capable of translating the smallest right hand nuance as clearly as the most powerful rhythmic passage. It must also record beautifully, with clarity across the full spectrum and enough natural warmth to make every note feel alive. This model was created around those needs, and the result is an OM that feels intimate, responsive, and deeply musical in the hands.
This particular guitar is only the sixth Antoine Dufour Signature Model ever built by Mario Beauregard, making it a remarkably rare example of an already highly specialized collaboration. The voice is centered around a Western Red Cedar top, chosen for its warmth, quick response, and expressive dynamic range. Cedar is especially well suited to a nuanced fingerstyle approach, offering a played in immediacy from the first touch while retaining the headroom and complexity needed for a world class performance instrument. Paired with Old Growth Indian Rosewood back and sides, the tone gains depth, overtone richness, and a refined low end that supports the guitar’s lyrical character without overwhelming its balance.
The build is visually striking in the way only a Beauregard can be. Indian Rosewood bindings frame the body with quiet sophistication, while Curly Maple top purfling adds a crisp, elegant contrast against the warm cedar top. The Quilted Sapele and Abalone rosette provides a beautiful focal point, tasteful and luminous without ever feeling excessive. The Florentine cutaway gives the guitar a graceful silhouette and effortless access to the upper register, which is essential for the kind of extended melodic and harmonic vocabulary associated with Antoine’s playing.
The neck is Honduran Mahogany, finished in black for a sleek and dramatic visual statement. An Ebony fingerboard and Ebony bridge provide the feel, durability, and tonal focus expected from an instrument of this caliber. The headstock is equally considered, with an Ebony front veneer and Burl rear veneer that give the guitar a boutique, artful presence from every angle. Gotoh 510 tuning machines in Black Chrome offer the smoothness, precision, and stability needed for altered tunings and demanding performance work, while Ebony pins complete the instrument with understated class.
The dimensions are perfectly suited to a serious fingerstyle player. A 1.75 inch nut width provides comfortable string separation for complex voicings and independent voices, while the 2.25 inch bridge spacing gives the right hand the room it needs for articulation, dynamics, and control. The 25 inch scale length offers a slightly more relaxed feel than a full long scale instrument, making the guitar comfortable and expressive while still maintaining excellent clarity and tuning stability. At 4 lb 11 oz, it has a substantial, confidence inspiring presence without feeling overbuilt or heavy in the lap.
Also included with this guitar is the Legacy pickup system, a thoughtfully designed solution for players who need professional amplified sound without compromising the integrity of the instrument. The pickup itself is a humbucking soundhole unit that can be installed or removed from the guitar in seconds. A quarter inch jack is installed in the guitar, with a mini plug connection for the pickup while in use. The most remarkable part of the system is its purely tube, no solid state preamp, housed externally in pedal form. That means the power supply and preamp do not need to be permanently installed inside the guitar, preserving the guitar’s acoustic purity while still offering a serious, high quality amplified signal when needed.
Elegant, rare, and deeply purpose built, this Mario Beauregard Antoine Dufour Signature OM is far more than a collectible signature model. It is a professional level creative instrument, designed for the demands of modern fingerstyle performance and recording, and executed by one of the finest luthiers in the world. With its Western Red Cedar top, Old Growth Indian Rosewood body, refined appointment package, removable Legacy pickup system, and historic status as only the sixth Antoine Dufour Signature Model ever made, this guitar stands as a breathtaking example of what can happen when a master builder and a visionary player pursue the same ideal.
