Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage open-gear design with precision engineering and smooth performance. Featuring an open-gear architecture with a worm gear drive, it delivers accurate tuning stability and reliable operation for discerning musicians.
With an 18:1 gear ratio, this tuning machine provides precise tuning and lasting durability. The deliberate absence of synthetic polymer coatings allows the unit to resonate naturally with your instrument, ensuring unimpeded acoustic response.
Built with ultra-precise contact surfaces and permanently sealed screw joints, the mechanism offers wear-free and maintenance-free longevity. Designed to fit standard production instrument dimensions, it enables clean retrofitting and secure string tension transfer.
