The Stay-In-Tune™ process is S.I.T.'s proprietary string manufacturing process designed to reinforce one of the most important areas of the string: the ball-end twist.
During manufacturing, we use a specialized bonding treatment to strengthen the twist where the string is secured at the ball end. This reinforcement helps prevent the twist from slipping under tension and promotes dependable tuning stability.
The Stay-In-Tune™ process is also where the S.I.T. name comes from: Stay-In-Tune™.
