Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines classic open-gear vintage aesthetics with precise tuning performance. Built with an open gear and worm drive architecture, this tuning machine delivers smooth operation and consistent pitch stability. Its precise 1:18 gear ratio provides ultra-fine tuning control designed for longevity and demanding musical performance.
Crafted without synthetic polymer coatings, the contact surfaces and precision fittings ensure optimal resonance transfer and natural stick-slip properties. Permanently locked, sealed, and joined screw connections provide wear-free and maintenance-free durability throughout years of playing.
Designed to fit standard production instrument dimensions for seamless installation and replacement, each solid headstock unit includes mounting screws and a hexagonal press-in bushing. Recessed screw holes ensure firm anchoring and enhanced acoustic transmission to the headstock.
