Schaller GrandTune Single Guitar Tuning Machine

The Schaller GrandTune Single combines refined vintage styling with precise tuning accuracy and ultra-smooth operation. Designed as a perfected open-gear tuning machine, it features an open gear and worm drive mechanism crafted without synthetic coatings for pure acoustic resonance.
Featuring an 18:1 gear ratio, this tuner delivers unmatched stability and long-lasting durability. Ultra-precise contact surfaces eliminate wear and stick-slip effects, while permanently locked and sealed screw joints provide maintenance-free performance across the life of your guitar.
Designed to fit standard production instruments, it includes recessed screw holes for secure mounting and optimal acoustic coupling. Solid headstock versions include matching hexagonal press-in bushings and mounting screws for straightforward installation.
