Product: Roller string tree retainer guide for electric guitars Short description Replacement roller string trees designed to take the place of damaged or worn string retainers on electric guitars. They reduce string pressure at the nut, minimize friction and wear, and help extend string life while promoting smoother tuning and string movement. Key benefits Reduces string pressure and friction at the headstock, lowering wear on strings and nut slots. Roller design lets strings glide smoothly, improving tuning stability during bends and tremolo use. Simple replacement for damaged, broken, or old string retainers, restoring proper string angle and contact. Suitable for players, learners, and hobbyists who need a functional replacement part for electric guitars. Features and attributes Function: Roller string tree retainer that guides and stabilizes strings between the nut and tuning posts. Compatibility: Fits most electric guitar headstock layouts that require a string tree or retainer; can be used where a rollerstyle guide is preferred. Check your instrument for a matching mounting hole pattern before installation. Size: Standard dimensions for common electric guitar applications; compact headstock footprint. Material and performance: Durable construction intended to reduce friction and wear while providing consistent string movement across the rollers. Installation: Designed for straightforward replacement of existing string trees; mounts in the same position as the original retainer. Practical use scenarios a broken or corroded string retainer on an electric guitar to restore proper string angle and reduce buzzing or binding at the nut. Upgrade a fixed string tree to a roller model to improve tuning stability when using a tremolo system or performing frequent bends. Routine instrument maintenance for learners and hobbyists who want to extend string life and keep the headstock hardware functioning smoothly. What to expect Restored string routing and reduced friction where the string contacts the headstock. More consistent tuning behavior under dynamic playing and lower wear on strings and nut. A reliable replacement part that returns a worn instrument to working condition without complex modification. Notes Confirm that your guitar has the correct mounting hole spacing and requires a string tree before .
