La Bella Stainless Steel Jazz Flats® were developed by the best jazz guitarists in the world. Each string is hand-wound and polished by our artisans in New York, resulting in a super smooth surface eliminating finger noise and squeaks. Optimized with a high magnetic content for increased electronic output, La Bella Jazz Flats® have a very bright sound and long playing life. These professional Jazz Guitar Strings are made to fit archtops and hollow-body guitars, therefore are NOT suitable for standard solid-body rock guitars with 25.5” or 24.75” scale like a Stratocaster® or Les Paul® model.
