Schaller GrandTune Guitar Tuning Machine

The Schaller GrandTune combines refined vintage aesthetics with precise tuning performance and ultra-smooth operation. Designed as an open-gear tuning machine with an exposed worm gear, it delivers exceptional acoustic resonance without synthetic coatings dampening instrument vibrations.
Featuring an accurate 1:18 gear ratio, this machine head offers precise intonation and reliable tuning stability. Ultra-precise tolerances and contact surfaces ensure optimal stick-slip behavior without wear or material aging, while permanently locked and sealed screw connections guarantee zero-maintenance longevity.
Engineered to standard instrument dimensions for straightforward replacement or installation, each unit includes recessed screw holes for secure mounting and maximum resonance transfer across the headstock.
