Ovation guitar

Ovation guitars have a history of innovative design, reflecting its founder's engineering training and development of Kaman helicopters. Ovation guitars have composite synthetic bowls; earlier acoustic guitars have had wooden sides abutting a flat back since the 1700s. Kaman diagnosed structural weaknesses in the orthogonal joining of the sides, and felt that a composite material could be used for a smooth designed body. Ovation's parabolic bowls dramatically reduced feed-back, allowing greater amplification of acoustic guitars. Improved synthetics used techniques from helicopter engineering to control vibrations in the bowl. Ovation has developed a thin neck, with the feel of an electric-guitar's neck, but with additional strength from layers of mahogany and maple reinforced by a steel rod in an aluminum channel. The composite materials and thin necks reduced the weight of Ovations.
