S.I.T. Strings is a full-line American manufacture of bass strings, guitar strings, and musical instrument accessories based in Akron, Ohio. The company was founded on a belief that a string is more than just an accessory, but rather an integral part of a musician’s sound and voice. That is why since 1980, S.I.T. (Stay-In-Tune) has been manufacturing the highest quality strings and accessories. www.sitstrings.com
