The Schaller GrandTune Single Guitar Tuning Machine combines elegant vintage styling with exceptional tuning precision and ultra-smooth operation. Designed as an open-gear tuner with a precision worm drive, it features an 18:1 gear ratio for meticulous accuracy and long-term durability on any instrument.
Built without synthetic coatings, the tuner provides pure acoustic resonance and a wear-free mechanism that maintains tone and stability throughout years of use. Ultra-precise contact surfaces ensure smooth movement without sticking, while permanently locked and sealed screw joints deliver maintenance-free performance.
Engineered to standard instrument dimensions for straightforward installation and replacement, this tuning machine includes countersunk mounting screw holes for firm coupling and optimal sound transfer across classic and contemporary guitars.
