Eastman E20SS-TC Sunburst Thermo Cured

Thermo Cured: a "vintage" approach at the heart of a modern dreadnought

The E20SS-TC stands out with its Thermo Cured (thermal treatment) top designed for increased stability and a mature tonal feel from the very first hours of playing. With its 16" body size and power-oriented construction, it fits the profile of a characterful acoustic guitar: responsive to pick attack, rich in harmonics, and crafted to support both accompaniment and fingerpicking.

Who is it for, and what styles?

This guitar is aimed at intermediate to advanced players seeking an expressive and dynamic acoustic capable of handling energetic playing without distortion. It excels in folk, bluegrass, country, and acoustic pop, while remaining very inspiring for fingerstyle thanks to the clarity of the ebony fingerboard and the overall balance of the body.

Sound

The combination of solid Adirondack spruce and solid rosewood delivers a sonic signature that is both broad and defined: Adirondack provides a crisp attack, strong hold at high volume, and excellent articulation, while rosewood enhances bass depth, treble brightness, and harmonic richness. The hand-scalloped X bracing allows for a freer top: the guitar projects easily, with generous sustain and clear note separation, especially appreciated in open chords as well as melodic lines.

Recommended Compatible Accessories

To maintain the original feel and balance, opt for phosphor bronze acoustic strings in .012 - .053 gauge. An acoustic guitar capo and picks (from flexible to stiff depending on the desired attack) will effectively complement the setup. Since this is a solid wood guitar, using an instrument humidifier can also help preserve the stability of the lutherie depending on your indoor climate.
