Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage open-gear design with precision engineering and exceptionally smooth tuning performance. Featuring an open-gear architecture with a threaded worm drive, it delivers classic aesthetics paired with modern build quality.
A precise 1:18 gear ratio provides outstanding tuning accuracy and long-term durability. By omitting synthetic polymer coatings, the tuner acts as a fully resonating unit that enhances overall tone and instrument resonance without wear or aging of internal contact surfaces.
Engineered with permanently locked, sealed screw connections for maintenance-free operation, it adheres to standard instrument dimensions for effortless installation and replacement. Countersunk screw holes ensure secure mounting and optimal acoustic transmission.
