Schaller GrandTune Single Guitar Tuning Machine

The Schaller GrandTune Single combines refined vintage aesthetics with precise tuning response and exceptionally smooth performance. Built as an open-gear tuner with an optimized worm gear mechanism, it delivers superior longevity and acoustic resonance without relying on synthetic coatings.
A precise 1:18 gear ratio ensures accurate and effortless tuning. Ultra-precise contact surfaces eliminate stick-slip motion and wear, while permanently locked and sealed screw joints provide maintenance-free durability across years of playing.
Engineered to standard instrument dimensions for straightforward installation and replacement, this tuning machine features countersunk mounting holes for a secure fit and optimum sound transmission to the headstock.
