Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single delivers an advanced combination of vintage aesthetics, precise tuning action, and smooth performance. Engineered as a refined open-gear tuning machine, it features an exact 1:18 gear ratio that provides lasting durability and accurate pitch adjustments.
Built without synthetic polymer coatings, this tuning machine maintains natural resonance across the entire headstock. The ultra-precise contact surfaces produce frictionless operation without wear or material degradation over time.
Equipped with permanently locked and sealed screw joints, the mechanism ensures maintenance-free longevity. Standard dimensions and countersunk screw holes allow direct replacement and secure mounting on standard guitar headstocks.
