Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single delivers a refined fusion of classic vintage aesthetics, precise tuning stability, and exceptionally smooth performance. Engineered with an open-gear design and precision worm screw, it serves as a perfected traditional tuning machine for discerning musicians and luthiers.
Featuring an 18:1 gear ratio, this tuning machine provides meticulous tuning accuracy and lasting durability. The deliberate absence of synthetic polymer coatings creates ideal stick-slip properties and ensures natural instrument resonance without wear or material degradation over time.
Built with permanently locked and sealed screw connections for maintenance-free operation, the GrandTune is sized to standard production instrument dimensions for seamless installation or replacement. Countersunk screw holes ensure secure mounting and optimal acoustic transmission.
