Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage styling with precise tuning response and ultra-smooth operation. Designed as an open-gear tuning machine, it features an exact 1:18 gear ratio that delivers exceptional precision, stability, and lasting performance without synthetic coatings.
Engineered with ultra-precise contact surfaces and permanently sealed screw joints, this tuning machine provides wear-free, maintenance-free functionality. The countersunk screw holes ensure secure mounting and optimal acoustic resonance transfer to the headstock.
Standardized dimensions allow seamless retrofitting and installation on factory production instruments. Each single tuner comes complete with countersunk mounting screws and a hexagonal press-in bushing for solid headstock configurations.
