Alvarez MF66ce Masterworks Solid Mahogany OM - Shadowburst
For players who believe the OM body shape is the ultimate expression of balance and clarity, the Alvarez MF66ce Masterworks Solid Mahogany OM delivers warmth, focus and fast response in a beautifully refined package. Finished in a rich Shadowburst gloss, this is an understated yet deeply expressive instrument built for nuance and precision.
Constructed with solid African mahogany for the top, back and sides, the MF66ce produces a warm, woody voice with exceptional midrange presence and clear, defined bass. Mahogany’s natural compression gives notes a rounded character, while the OM body shape ensures outstanding string-to-string balance and articulation. It’s an incredibly connected-feeling guitar — responsive to touch, dynamic and accurate.
To enhance projection and openness, Alvarez pairs the all-mahogany build with its FS6 forward-shifted, scalloped X-bracing system. This lighter-weight bracing design allows the top to move more freely, broadening the tonal spectrum beyond what many expect from mahogany-topped guitars. The result is impressive clarity, quick attack and sparkling high-end detail without losing warmth.
The OM size is especially loved by fingerstyle players, light strummers and those who value articulation over sheer volume. It offers comfort, precision and an eloquent voicing that adapts beautifully across genres — from folk and blues to contemporary acoustic styles.
Aesthetically, the MF66ce blends traditional craftsmanship with modern refinement. The Shadowburst gloss finish adds vintage-inspired depth, while premium appointments elevate the overall feel. The African mahogany neck meets the body at the 14th fret and features 22 frets for extended playability. An East Indian rosewood fingerboard and headstock fascia, Bi-Level Indian rosewood bridge, bone nut and saddle, ebony bridge pins and premium MOP inlays complete the elegant look. Open-gear tuners provide smooth, precise tuning with classic styling.
Like all Masterworks models, the MF66ce benefits from ATR™ (Advanced Tonal Response) treatment. Through oxygen-controlled curing and thermo-kiln drying, the wood behaves more like a mature instrument from day one — offering improved stability, enhanced resonance and superior note separation.
For stage and studio, the MF66ce is equipped with the LR Baggs HiFi pickup system, delivering natural, balanced amplified tone with excellent feedback resistance. It’s a reliable, high-fidelity system that preserves the guitar’s organic voice.
The guitar ships in Alvarez’s durable AFC30 Flexicase, ready for rehearsals, gigs and travel.
This is an OM for players who want warmth without muddiness, clarity without brittleness and a beautifully balanced voice that rewards expressive playing.
