Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single tuning machine combines refined vintage aesthetics with precise tuning performance and velvety smooth action. Designed with an open gear and worm drive architecture, it provides an exact 1:18 gear ratio for superior tuning accuracy and enduring stability. The absence of synthetic coatings allows for natural acoustic coupling and optimal instrument resonance.
Engineered with ultra-precise contact surfaces, the GrandTune mechanism delivers frictionless movement without wear or degradation over time. Permanently locked, sealed screw joints ensure completely maintenance-free operation across years of play. Standard mounting dimensions allow for direct installation and replacement on standard guitar headstocks.
Recessed mounting screw holes ensure secure contact and seamless tone transfer to the wood. Deluxe string roller configurations feature integrated ball bearings at the shaft ends to eliminate friction and creaking inside the peghead bore for effortless nylon string tuning.
