The Adamas brand is owned by the Kaman Music Corporation. Adamas guitars were originally marketed as a high end series of Ovation guitars, between 1976 and the late 1990s. Since then they have been produced as a brand in their own right.

The carbon fibre production techniques pioneered in Adamas guitars were developed by Charlie Kaman after working in the aviation industry. Adamas claim their guitars are the most technolgically advanced ever built. These guitars have the typical Ovation style round backs, but have carbon fiber tops and multiple soundholes.
