The Schaller GrandTune represents an exceptional combination of vintage aesthetics, precise tuning accuracy, and velvet-smooth performance. Crafted as a perfected classic open-gear tuner with worm gear architecture, it ensures maximum resonance on any instrument by entirely omitting synthetic polymer coatings.
Equipped with an 18:1 gear ratio, this tuning machine provides uncompromising precision, durability, and tuning stability. Ultra-precise fittings and contact surfaces deliver optimal stick-slip action free of wear or aging, while permanently locked and sealed screw joints guarantee maintenance-free reliability.
Designed to fit standard production instrument dimensions for seamless installation or replacement, it features countersunk screw holes that ensure firm anchoring and enhanced acoustic transmission.
