Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune represents the ultimate fusion of stylish vintage design, precise tuning, and ultra-smooth performance. Crafted as a perfected classic tuning machine with open-gear architecture and threaded worm gear, it delivers an 1:18 gear ratio for unmatched tuning accuracy and long-term durability.
Built without synthetic polymer coatings, the ultra-precise contact surfaces ensure optimal stick-slip properties free from wear or aging. Permanently locked, sealed screw joints provide maintenance-free operation, while countersunk screw holes ensure secure mounting and flawless acoustic resonance.
Engineered to standard instrument dimensions for effortless retrofitting, each single tuning machine comes with mounting hardware and hexagonal press-in bushings for solid headstock installations.
