Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines vintage aesthetic architecture with modern mechanical precision, featuring an open-gear configuration and precision threaded worm design. Engineered without synthetic coatings, the solid metal components deliver unimpeded acoustic resonance directly through the instrument's headstock.
A precise 1:18 gear ratio provides ultra-smooth, pinpoint tuning accuracy and long-term mechanical reliability. The contact surfaces and ultra-precise fittings ensure optimal stick-slip movement without degradation or wear over time.
Permanently locked and sealed screw joints provide maintenance-free operation across years of continuous performance. Designed to match standard production instrument dimensions, it enables clean integration and direct retrofitting.
