Schaller GrandTune Single Guitar Tuning Machine

The Schaller GrandTune combines refined vintage styling with ultra-precise tuning response and velvet-smooth performance. Built as a perfected open-gear tuning machine with exposed worm gears, it delivers uncompromised mechanical reliability and timeless aesthetic appeal.
Featuring a precise 1:18 gear ratio, this tuner provides exacting intonation control and long-lasting durability. The intentional elimination of synthetic coatings ensures seamless resonance transfer directly through the headstock, preserving the natural tone and sustain of your instrument.
Crafted with ultra-precise contact surfaces and permanently sealed screw joints, the mechanism ensures wear-free and maintenance-free operation. Standardized housing dimensions and countersunk mounting holes facilitate seamless retrofitting on conventional solid and slotted headstocks.
