Eastman Guitars E10OOSS-TC Thermo-Cured Adirondack Sunburst OO Slope Shoulder

Eastman E10OOSS-TC Thermo-Cured Adirondack OO Acoustic Guitar

There is something special about a great small-body mahogany guitar. The Eastman E10OOSS-TC combines the character of a vintage-inspired slope-shoulder design with the exceptional materials and craftsmanship that have made Eastman one of the most respected names in boutique-quality acoustic guitars.

This 14-fret OO-size guitar features a solid Thermo-Cured Adirondack Spruce top paired with beautifully figured solid mahogany back and sides. Add Eastman’s hand-carved scalloped X-bracing, a comfortable 24.75” scale length, and a stunning vintage sunburst finish, and you have a guitar that delivers an incredible combination of tone, feel, and visual appeal.

And perhaps best of all, the E10OOSS-TC brings much of the look, construction, and character associated with far more expensive boutique instruments to a considerably more accessible price point.

✅ Why You’ll Love This Guitar

The E10OOSS-TC is a guitar that feels immediately familiar. Its OO body and slope-shoulder design take inspiration from some of the most beloved vintage Gibson L-00-style instruments, while Eastman’s modern craftsmanship and premium materials give it a voice all its own.

The combination of Thermo-Cured Adirondack Spruce and mahogany produces an especially appealing acoustic personality: strong fundamental notes, excellent clarity, woody warmth, and plenty of headroom when you dig in.

It’s equally comfortable on the couch, in the studio, or on stage.

✅ Why We Chose This Guitar

We have been an Eastman dealer for nearly 20 years, and we’ve watched the company consistently raise the bar for what is possible at its price points.

The E10OOSS-TC is a perfect example.

You get a solid Thermo-Cured Adirondack Spruce top, solid mahogany construction, hand-carved scalloped X-bracing, ebony fingerboard, premium appointments, and a beautifully executed gloss finish—the kind of specification package we normally associate with considerably more expensive guitars.

For players looking for a boutique-quality instrument without a boutique-level price tag, this one is particularly compelling.

✅ Our Expert Opinion

The OO body size is one of our favorite acoustic guitar designs. It is comfortable, responsive, and incredibly versatile.

What makes this Eastman particularly interesting is the slope-shoulder design combined with the 14-fret neck joint. The guitar has a vintage-inspired look, but the 14-fret configuration gives it a little more modern versatility and a comfortable playing feel.

The Thermo-Cured Adirondack top is the real star of the show. It gives this guitar an impressive combination of clarity, responsiveness, projection, and dynamic range, while the mahogany body supplies the warm, woody character that makes these guitars so addictive to play.

And visually, this is one beautiful guitar. The vintage sunburst over the Adirondack top and the figured mahogany back and sides give the E10OOSS-TC a distinctly vintage personality.

✅ Tone Profile

Warm • Woody • Punchy • Clear • Responsive

The mahogany body emphasizes strong fundamentals and a dry, woody character, while the Thermo-Cured Adirondack Spruce top adds clarity, headroom, and impressive projection.

The smaller OO body produces a focused and intimate voice without sounding small. It responds beautifully to fingerstyle playing but has plenty of punch when played with a pick.

This is a particularly good choice for players who love the dry, direct character of vintage mahogany guitars but want the added responsiveness and dynamic range of an Adirondack spruce top.

✅ Tobias Music Insight

Small-body guitars have become increasingly popular, and for good reason. They are comfortable, responsive, and often have a character that larger guitars simply can’t duplicate.

The E10OOSS-TC takes that concept a step further by combining the intimate voice of an OO guitar with Thermo-Cured Adirondack Spruce and a slope-shoulder design inspired by vintage Gibson instruments.

If you’re looking for a guitar that feels special the moment you pick it up—but doesn’t require a five-figure investment—this Eastman deserves a serious look.

Boutique character. Vintage inspiration. Exceptional materials. Remarkable value.

That’s the Eastman E10OOSS-TC.
