Schaller GrandTune Guitar Tuning Machine

The Schaller GrandTune combines refined vintage styling with precise tuning accuracy and ultra-smooth operation. Designed as a perfected open-gear tuning machine, it features exposed gears and precision worm drives for exceptional resonance and feel.
A 1:18 gear ratio delivers fine-tuning control and enduring reliability. Manufactured without synthetic polymer coatings, the tuner promotes natural instrument resonance while ultra-precise contact surfaces provide smooth stick-slip performance without wear or aging.
Engineered to standard instrument dimensions for straightforward installation and replacement, each tuner includes permanently locked and sealed screw connections along with countersunk mounting holes for secure anchoring and optimal sound transmission.
