La Bellas stainless-steel 20P Jazz Flats electric guitar strings were developed by the best jazz guitarists in the world. Each string is handwound and polished by La Bellas 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 20P Jazz Flats have a very bright sound and long playing life. La Bella has recently improved their string construction to fit more models and prevent overtones.
