Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines classic vintage styling with precise tuning performance and smooth operation. Designed as an open-gear tuner with a precision worm gear mechanism, it features a 1:18 gear ratio for accurate tuning and dependable long-term stability. The synthetic-coating-free construction allows the component to resonate naturally with the instrument.
Crafted with ultra-precise contact surfaces and permanently locked, sealed screw joints, this machine head delivers wear-free and maintenance-free longevity. Standard dimensions ensure compatibility and straightforward installation or replacement on standard production guitar headstocks.
Recessed screw holes provide a secure mechanical mount and optimal acoustic coupling to the headstock. Depending on the selected configuration, it installs cleanly onto solid or slotted pegheads without unnecessary friction.
