Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines classic vintage styling with exact tuning stability and ultra-smooth operation. Designed as an open-gear tuner with an optimized worm gear mechanism, it provides an uncompromising blend of traditional aesthetics and modern precision craftsmanship.
Featuring a 1:18 gear ratio, this tuning machine enables exceptionally fine adjustments and reliable pitch control. The elimination of synthetic polymer coatings ensures optimal resonance transfer to the instrument headstock while maintaining wear-free performance across its entire lifespan.
Built with permanently locked, sealed screw joints and recessed mounting holes, the GrandTune guarantees a maintenance-free fit and maximum acoustic transmission across acoustic, classical, and electric guitars.
