Eastman E20OML-TC Natural Thermo Cured LH

A modern OM with a "vintage" character thanks to Thermo Cure

The E20OML-TC embodies the spirit of OM guitars known for their versatility and tonal balance. The Thermo Cure treatment applied to the top aims to stabilize the wood and bring the response closer to that of a well-played guitar: increased responsiveness, better perceived projection, and a harmonic output that settles quickly. Combined with hand-scalloped X bracing, this lutherie emphasizes vibration, nuance, and precision while maintaining a comfortable foundation in the lower spectrum.

For which guitarists and styles?

Thanks to its short scale length, wide nut, and OM format, this guitar is particularly suited for intermediate to advanced players seeking an expressive acoustic, equally comfortable in fingerstyle, folk, blues, or pop accompaniment. The nut width facilitates ease for both right and left hands when playing arpeggios, voicings, and picking patterns. The traditional "C" profile and ebony fingerboard provide a sense of control and clarity, ideal for working on precision and nuanced attacks.

Sound

The thermo-treated solid Adirondack spruce top offers a clear attack and a wide dynamic range: the harder you play, the more the guitar responds without compressing, while remaining sensitive to light playing. The solid rosewood back and sides enrich the spectrum with ample lows, bright highs, and generous sustain, delivering a sense of depth and a very appreciable "width" in solo playing. The hand-scalloped X bracing promotes projection and openness in the midrange, helping the guitar stay clear in an acoustic mix. Overall, it delivers a typically OM balance: defined, articulate, yet never thin, with a beautiful note separation.

Recommended compatible accessories

To get the most out of this acoustic, you can choose a set of acoustic guitar strings (bronze or phosphor bronze, depending on whether you want more brightness or warmth), a tuner (clip-on or pedal), and a humidifier to protect the solid woods during dry periods. A standard capo for acoustic guitars is also suitable for exploring other keys without changing your fingerings.
