Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage design with precise tuning and ultra-smooth performance. Built as a perfected open-gear tuning machine with exposed gear and worm drive, it delivers exceptional acoustic resonance without synthetic coatings.
Featuring a 1:18 gear ratio, this tuning machine provides unmatched tuning accuracy and long-lasting durability. Ultra-precise fittings and contact surfaces prevent wear and aging, while permanently locked and sealed screw connections ensure completely maintenance-free operation.
Designed around standard production instrument dimensions, the GrandTune allows for hassle-free installation and replacement. Countersunk screw holes ensure a firm hold and optimal tone transmission directly into the headstock.
