Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single guitar tuning machine combines classic vintage design with exact tuning accuracy and smooth performance. Engineered as a perfected open-gear tuning mechanism with a worm gear architecture, it ensures reliable resonance and durability without synthetic coatings.
Featuring a precise 1:18 gear ratio, this machine head provides responsive, velvet-smooth tuning stability for your instrument. Ultra-precise contact surfaces eliminate stick-slip motion without wearing out over time, while sealed and permanently locked screw joints ensure maintenance-free operation.
Designed to fit standard production instruments, it includes countersunk screw holes that ensure solid mounting and optimal acoustic sound transmission. High-grade construction and wear-free mechanics make it an exceptional upgrade for both solid and slotted headstock guitars.
