Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single brings together refined vintage aesthetics, precise tuning capability, and ultra-smooth operation. Designed as an open-gear tuner with a precision worm gear mechanism, it provides an exact 1:18 gear ratio for fine adjustments and lasting tuning stability.
Crafted without synthetic polymer coatings, its ultra-precise contact surfaces allow natural acoustic resonance while eliminating wear and aging. Permanently locked, sealed screw joints ensure zero-maintenance performance and long-term durability across demanding playing conditions.
Engineered to standard instrument dimensions for effortless installation and retrofitting, this tuning machine features countersunk mounting holes for a secure fit and optimal tonal transfer. Each solid headstock unit includes mounting screws and a matching hexagonal press-in bushing.
