Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage styling with precise tuning behavior and smooth performance. Designed as an open-gear tuner with an exposed worm gear, it delivers classic aesthetics alongside modern mechanical engineering.
Featuring an 18:1 gear ratio, this tuning machine provides precise adjustments and lasting durability. The absence of synthetic coatings allows optimal acoustic resonance across your instrument, while precision contact surfaces resist wear and degradation over extended use.
Permanently locked and sealed screw joints provide maintenance-free operation. Engineered to fit standard production instrument dimensions, it integrates smoothly onto compatible guitar headstocks with countersunk mounting holes for secure anchoring and clean tonal transfer.
