The Schaller GrandTune combines classic vintage aesthetics with precise tuning response and ultra-smooth operation. Designed as an open-gear tuner with a precision worm drive, it delivers exceptional tonal resonance across acoustic, electric, and classical instruments.
A precise 1:18 gear ratio ensures accurate tuning stability and long-lasting durability. Manufactured without synthetic polymer coatings, the contact surfaces provide stick-slip-free movement while sealed screw fittings eliminate wear and maintenance requirements.
