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.
