Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage aesthetics with precise tuning response and smooth performance. Built as an open-gear tuning machine with an exact worm gear design, it delivers outstanding tuning accuracy and long-lasting durability through its 1:18 gear ratio.
Crafted without synthetic polymer coatings, the ultra-precise contact surfaces create frictionless stick-slip performance without wear or aging. Permanently locked, sealed screw joints ensure completely maintenance-free operation, while countersunk screw holes provide firm seating and optimal resonance transfer to the instrument headstock.
Designed with standard instrument dimensions for straightforward installation and replacement, this tuning machine seamlessly matches premier guitars. String Roller Deluxe configurations feature an additional ball bearing at the post end to ensure noiseless, low-friction string adjustments.
