Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage styling with precise tuning response and ultra-smooth operation. Designed as an open-gear tuner with an exposed worm and gear mechanism, it delivers exceptional mechanical accuracy and timeless aesthetics.
Featuring a 1:18 gear ratio, this tuning machine provides precise control and long-lasting durability. The absence of synthetic coatings ensures unrestricted resonance across the instrument, while ultra-precise contact surfaces prevent premature wear and material fatigue.
Equipped with permanently locked and sealed screw connections, the GrandTune offers maintenance-free performance. Its dimensions align with standard instrument headstock specifications for straightforward installation and direct replacement.
