Ovation acoustic guitars are instantly recognizable - not just for their clear, balanced tone, but especially because of their unique roundback design that makes way for superb projection. There's more to the Ovation roundback story than mere design happenstance. Charlie Kaman, an aeronautical engineer and longtime guitarist, blended his two passions by applying his aerospace knowledge of creating and controlling vibration to the music world where vibration is king! Most all groundbreaking innovation requires the audacity to break conventions, and that's just what Kaman and his team did when developing the now-acclaimed roundback Ovations.
