Adamas

I GT 1687GT

The World’s Most Advanced Acoustic Guitar

Representing the ultimate craftsmanship from Ovation’s flagship workshop in New Hartford, Connecticut, the Adamas 1687 GT features a unidirectional carbon-graphite suspended soundboard with Quintad bracing, which provides a bold, clear voice and lightning-fast response. Each top is precisely fitted with “AST” – Adamas Suspended Top – technology that allows the ultra-thin top to vibrate more freely than traditionally constructed acoustic guitars.

The non-cutaway Deep Bowl composite body is made by hand from fiberglass cloth and works in tandum with the top to enhance frequency response and improve projection. The Adamas GT’s detailed ornamentation—including a carved peghead scroll, carved walnut bridge, and elaborately decorated soundholes—make a striking visual statement.

Deep Bowl

Ovation’s Deep Bowl body generates maximum unamplified volume and enormous low end, yet it’s easier to hold and play then a traditional jumbo-body guitar. Models sporting Deep Bowl bodies also perform impressively when plugged in, thanks to Ovation’s advanced onboard electronics. A “sonic cannon” that shines either unplugged or through a sound system or stage amp, a Deep Bowl Ovation offers the best of both electric and acoustic worlds.


OP-Pro Studio with XLR

The OP-Pro Studio with XLR combines state-of-the-art audio quality with exclusive features designed to meet the needs of professional guitarists. The easy-to-operate unit offers 3-band EQ, exciter and compressor/limiter circuitry, and a chromatic tuner. Ovation’s exclusive Expressor and Drive sliders put dynamic control and harmonic enhancement at your fingertips, allowing you to precisely dial in the sustain and punch you need. The XLR jack provides a balanced line connection to mixers, recording consoles, and high-end acoustic amps. It also provides phantom power to the OP-Pro—an essential feature for touring professionals.

Adamas

I GT 1687GT

The World’s Most Advanced Acoustic Guitar

Introduced in 1976, the Adamas was born of the same innovative spirit that developed the shape, design, and function of the Ovation Roundback®. Today, more than three decades after its introduction, the Adamas remains the most advanced acoustic guitar ever made.

Adamas is the Latin word for diamond in its native form—carbon. Kaman Aerospace used carbon fiber to make cutting-edge components for satellites and supersonic aircrafts. Realizing that carbon fiber had the potential to create a pure and balanced soundboard for his guitars, Charlie Kaman and his engineers began lab trials to create a carbon-fiber top for the Ovation. They discovered that when properly engineered, carbon fiber—or graphite—behaves very much like wood.

The Adamas soundboard is made from long fibers of aerospace-grade graphite designed to resonate and respond like spruce. At one-third the weight of a spruce top, the Adamas soundboard has a bold and clear voice, quicker response, and vibrates longer than a traditional spruce top. Adamas models feature Ovation’s pioneering Mid-Depth or Deep Bowl composite bodies.

More than 30 years since the first Adamas prototypes were introduced to the world and stage, Ovation engineers continue their R&D on this groundbreaking instrument and Charlie’s visionary concept. With its space-age materials and meticulous construction, the Adamas represents the perfect blend of art and science
