Sigma Acoustic Guitar OMM-ST Natural Satin Solid Sitka Spruce Top Mahogany Side and Back

Sigma OMM-ST Natural Satin – The Fingerstyle Virtuoso's Choice

Experience the refined elegance of the Orchestra Model with the Sigma OMM-ST. This OM-14 Fret body shape delivers the perfect balance of articulation, warmth, and projection, making it the definitive choice for fingerpickers, lead players, and discerning musicians who demand clarity across the entire tonal spectrum.

Premium All-Mahogany & Spruce Tonewood Combination
At the heart of this instrument lies a solid Sitka spruce top, celebrated for its dynamic range, brilliant highs, and remarkable responsiveness to every nuance of your playing. The mahogany back and sides provide a warm, focused midrange with a dry, fundamental tone that sits perfectly in any mix. The natural satin finish enhances the guitar's organic beauty while enabling the wood to resonate freely, delivering exceptional sustain and clarity.

Superior Playability for Demanding Players
The low-profile mahogany neck, shaped for effortless comfort, pairs seamlessly with a smooth Micarta fingerboard and bridge for fast, precise action. With a scale length of 25.4" (645 mm) and a generous nut width of 1-3/4" (44.5 mm), this guitar offers ample string spacing for intricate fingerstyle techniques, complex chord voicings, and fluid single-note runs. The wider nut accommodates both delicate picking and aggressive strumming with equal grace.

Precision Craftsmanship
Sigma's commitment to traditional lutherie is exemplified by the dovetail neck joint, ensuring superior vibration transfer from neck to body for enhanced sustain and tonal richness. The two-way truss rod provides adjustable neck relief, allowing players to customize action to their preferred feel and adapt to changing climates.

Premium Appointments for Professional Performance
The bone nut and saddle deliver superior sustain, improved intonation, and enhanced string vibration transfer compared to synthetic alternatives. Chrome die-cast tuning machines ensure precise, stable tuning, keeping your performance pitch-perfect through extended sessions.

Versatile Tonal Character
The OM body offers a balanced, articulate response with defined bass, clear mids, and sparkling highs. This versatile tonal palette excels in fingerstyle, flatpicking, and light strumming contexts, making the OMM-ST equally at home in the studio, on stage, or in intimate living room sessions.

The Sigma Heritage
Born from the legendary C.F. Martin tradition and now under meticulous German craftsmanship, Sigma continues a legacy of affordable excellence spanning over five decades. Every OMM-ST is built to inspire, combining timeless aesthetics with modern playability and exceptional value.
