Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single Guitar Tuning Machine combines vintage open-gear aesthetics with modern engineering precision. Featuring an ultra-precise 1:18 gear ratio, it delivers velvety smooth performance, pinpoint tuning accuracy, and long-lasting stability without synthetic coatings.
Built with non-wearing contact surfaces, permanently locked screw joints, and recessed screw holes, this tuner ensures optimal acoustic resonance and zero-maintenance durability. Standardized dimensions allow for straightforward installation and direct replacement on solid or slotted headstock instruments.
Each single unit comes complete with counter-sunk mounting screws and precision press-in hexagonal bushings where applicable. The refined construction eliminates frictional noise and stick-slip resistance, ensuring flawless tone transmission and exceptional instrument sustain.
