Eastman L-OOSS-KOA Natural

A "full koa" acoustic designed for the high-end market

The L-OOSS-KOA Natural stands out with a radical and prestigious choice: solid koa throughout the entire body. This approach highlights the wood's personality, with a guitar that gains complexity over time. Without onboard electronics, it prioritizes acoustic authenticity and fine craftsmanship, while showcasing a particularly refined visual identity (binding, rosette, markers, and logo in mother-of-pearl).

For which guitarist and styles?

Thanks to its 24.75" / 628.7 mm scale length and traditional neck profile, this guitar is aimed at intermediate to advanced guitarists seeking a soft touch, ideal for fingerstyle playing, nuanced accompaniment, and acoustic lead parts. It excels in folk, pop, blues, and fingerstyle, wherever dynamics, harmonic richness, and attack precision make a difference.

Sound

The solid koa delivers a balanced signature: present mids, a precise high end, and natural warmth that highlights expressive playing. The hand-sculpted X bracing promotes quick response and good projection while maintaining clear string-to-string definition. The combination of ebony fingerboard and bridge enhances clarity, attack, and control feel, while the bone nut helps maintain good articulation and natural sustain.

Recommended compatible accessories

To preserve the original setup and tension, prefer light steel strings 12-53 (such as the factory-installed D'Addario XS Coated Phosphor Bronze Light .012 - .053). A capo for 6-string acoustic guitar and a chromatic tuner are perfect for daily playing. To protect the solid woods, an acoustic guitar humidifier is also advisable in dry environments.
