Since 1980, S.I.T. Strings has been manufacturing high-quality guitar, bass, specialty strings, and accessories for musicians around the world. The name S.I.T. stands for “Stay-In-Tune,” a promise that reflects our mission to build strings with exceptional stability, tone, and reliability—made possible by precise engineering and a passion for music.

Every string we produce is American Made. Based in Akron, Ohio, our quality control is handled in-house from start to finish. We build, inspect, and package each product to exacting standards using premium U.S. materials. Our hands-on approach allows us to maintain the consistency that professionals demand while continuing to innovate in materials and design.

S.I.T. Strings are trusted by touring artists, studio musicians, and hobby players alike. From our flagship Power Wound Nickel electric guitar series to our signature artist lines and premium acoustic, bass, and specialty sets, we offer a full range of products designed to meet the needs of players in every style.

As an independent, family-owned American manufacturer, we take pride in supporting music at every level—from local players and educators to international distributors and OEM partners. Our artist roster spans genres and generations, with musicians who share our belief that a great string can inspire great music.

At S.I.T., we continue to evolve while staying true to our roots. We combine decades of craftsmanship with modern technology to produce strings that “Stay-In-Tune”—set after set, show after show.
