Schaller GrandTune Single Guitar Tuning Machine

The Schaller GrandTune Single represents the ultimate combination of stylish vintage design, precise tuning accuracy, and velvet-smooth performance. Built with an open-gear architecture and threaded worm gear, this classic tuning machine delivers exceptional acoustic resonance and tuning stability without relying on synthetic coatings.
Featuring a precise 1:18 gear ratio, this machine head provides unmatched tuning control and lasting durability. The ultra-precise contact surfaces generate ideal stick-slip characteristics free from wear or aging, while permanently locked and sealed screw joints ensure zero-maintenance operation over decades of play.
Engineered to standard instrument dimensions for trouble-free installation and direct replacement, each unit includes countersunk screw holes for solid anchoring and optimal sound transmission to the headstock.
