Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines sophisticated vintage design with precise tuning stability and exceptionally smooth performance. Engineered as a perfected open-gear tuning machine, it features an open gear and worm construction with a 1:18 gear ratio that delivers exceptional accuracy and lasting durability. The deliberate absence of synthetic coatings allows optimal acoustic resonance across your instrument.
Crafted with ultra-precise contact surfaces and zero polymer coatings, the GrandTune creates stick-slip-free operation immune to wear and material aging. Permanently locked, sealed, and enclosed screw connections provide maintenance-free longevity, while standard production dimensions ensure seamless installation or replacement on standard headstocks.
Equipped with countersunk screw holes for solid anchoring and enhanced sound transmission, this tuning machine maintains optimal tone and mechanical integrity. It is designed to match the lifespan and acoustic resonance of premium acoustic and electric guitars.
