Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage aesthetics with precise tuning behavior and smooth performance. This perfected open-gear tuning machine features an open gear design and worm gear architecture built for lasting reliability.
A precise 1:18 gear ratio delivers fine-tuning accuracy and operational stability. By omitting synthetic polymer coatings, the tuner acts as a resonant unit on the instrument, creating ideal stick-slip performance without premature wear or aging.
Engineered to standard instrument dimensions for straightforward installation and replacement, the tuning machine features permanently locked, sealed screw fittings and countersunk screw holes for solid mounting and resonance transfer.
