Schaller GrandTune Single 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 mechanism, it provides an optimal blend of classic design and modern acoustic performance.
Featuring an 18:1 gear ratio, this tuning machine delivers high accuracy and exceptional durability. The omission of synthetic coatings enables complete structural resonance, allowing the tuner to enhance instrument tone while maintaining wear-free mechanical engagement.
Ultra-precise contact surfaces eliminate stick-slip friction without polymer layers. Sealed and permanently locked screw joints ensure maintenance-free longevity, and standard dimensions allow direct installation or replacement on production instruments.
