Roller String Tree for Electric Guitar Key benefits Reduces string stress and friction at the headstock, lowering wear on strings and extending string life. Maintains consistent break angle and string alignment for improved tuning stability and smoother playing. Simple replacement or upgrade for damaged or worn string trees, restoring proper string path and performance. What it does Uses rotating rollers to minimize contact friction where strings pass over the tree, protecting strings and reducing breakage. Keeps string length and tension behind the nut consistent, which helps reduce tuning drift during bends and tremolo use. Supplied with mounting screws and ready to install for quick replacement. Materials and build Made from a hardness alloy for durable, longlasting performance and reliable rolling action. Solid construction resists wear from string contact and repeated tuning. Compatibility and fit Designed for electric guitars that use string trees or similar headstock mounts. Check your guitar for a compatible mounting hole and screw size before installation. Compact profile fits most standard headstock layouts without significantly altering string spacing. Performance and maintenance Roller design reduces friction and tuning problems caused by string binding. Requires minimal maintenance; occasional light lubrication on rollers can preserve smooth rotation. Easy to remove and reinstall with standard screwdriver. Typical use scenarios a broken or corroded string tree on an electric guitar to restore correct string path and reduce string breakage. Upgrade a fixed string tree to rollers on guitars equipped with tremolo systems to improve tuning stability during heavy tremolo use. Install on vintage or modern instruments that need smoother string movement at the headstock to reduce tuning friction and extend string life. What you receive Roller string tree assembly with rollers and mounting screws, ready for installation. Notes Verify compatibility with your guitar headstock and mounting screw spacing before installation.
