An "Old School" OM Spirit with a Thermo Cure Top
With its OM format and hand-scalloped X bracing, the E20OM-TC clearly targets a traditional tonal aesthetic: lots of clarity, a crisp attack, and even projection. The "Thermo Cure" feature (thermo-treatment of the top) aims to bring the wood's behavior closer to that of a played-in instrument by stabilizing the response and providing a sense of maturity right from the start. All finishes (herringbone purflings, abalone inlays, pearloid logo) reinforce this high-end positioning with a classic style.
For Which Guitarist and Styles?
This guitar is well suited for intermediate to advanced guitarists seeking an expressive and nuanced acoustic. The OM format excels particularly in fingerstyle, folk, picking, blues, vocal accompaniment, and pick playing with excellent dynamic control. The nut width and comfortable fingerboard radius promote precision, while the slightly shorter scale length helps achieve a flexible feel under the fingers, appreciated for light bends and long playing sessions.
Tone
The thermo-treated solid Adirondack spruce top provides a significant power reserve and excellent sustain when played aggressively, while maintaining great sensitivity to nuances. The solid rosewood back and sides enrich the harmonic spectrum: ample lows, full mids, and bright highs, with a sense of depth and sustain. The hand-scalloped X bracing promotes resonance and projection, while maintaining an articulated note-by-note response, particularly useful for open chord arrangements and simultaneous melodic lines.
Recommended Compatible Accessories
To get the most out of this format, an acoustic guitar capo and a tuner are simple and universal choices. An acoustic guitar humidifier is also recommended to protect the solid wood construction from humidity variations.
