Schaller GrandTune Guitar Tuning Machine

The Schaller GrandTune represents the ultimate fusion of elegant vintage design, precise tuning accuracy, and velvet-smooth performance. Built as an open-gear tuning machine with precision-crafted worm gears, it offers classic aesthetic appeal alongside cutting-edge mechanical engineering.
Featuring an ultra-precise 1:18 gear ratio, this tuning machine delivers exceptional tuning stability and long-lasting durability. The absence of synthetic coatings ensures pure acoustic resonance and optimal mechanical contact, allowing your instrument to vibrate naturally without dampening tone.
Equipped with permanently locked and sealed screw joints, the mechanism guarantees wear-free and maintenance-free operation. Engineered to standard instrument dimensions, it provides seamless installation and direct replacement for solid or slotted headstocks.
