Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single guitar tuning machine delivers a refined combination of vintage styling, pinpoint tuning stability, and smooth performance. Built with an open-gear design, it features an ultra-precise 1:18 gear ratio for exact adjustment and long-lasting durability.
Engineered without synthetic polymer coatings, this open-gear machine head creates optimal stick-slip properties that resist wear and aging. The design ensures resonant acoustic coupling, allowing the tuning mechanism to vibrate in harmony with the instrument.
Permanently locked and sealed screw connections provide maintenance-free reliability over years of use. Standardized dimensions ensure seamless replacement or straightforward installation on modern and vintage serial instruments alike.
