Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single provides a refined combination of vintage aesthetics, precise tuning behavior, and velvet-smooth performance. Featuring a perfected open-gear architecture with a worm gear mechanism, this tuning machine delivers exceptional tuning stability without the use of synthetic coatings for optimal acoustic resonance.
Equipped with a precise 1:18 gear ratio, it offers durable, wear-free performance across diverse playing styles. The ultra-precise contact surfaces eliminate polymer wear, while permanently locked and sealed screw connections ensure completely maintenance-free operation over extended use.
Engineered to standard instrument specifications, this single tuning machine enables straightforward retrofitting or installation. Recessed screw holes deliver firm mechanical coupling and enhanced acoustic transfer directly to the guitar headstock.
