Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage aesthetics with precise tuning response and ultra-smooth operation. Designed as an open-gear tuner with a precision worm gear, it delivers an optimal balance of classic architecture and modern engineering.
Featuring an 18:1 gear ratio, this tuning machine provides exceptional tuning accuracy and longevity. The design avoids synthetic coatings across its contact surfaces, allowing the tuner to resonate naturally with the instrument while maintaining wear-free performance.
Equipped with permanently locked and sealed screw connections, the unit offers maintenance-free reliability. Standard dimensions ensure seamless drop-in installation or replacement on standard headstocks, supported by countersunk mounting screw holes for firm resonance transfer.
