Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines vintage design with precise tuning behavior and smooth performance. This classic open-gear tuning machine features a worm gear architecture crafted to deliver exceptional resonance and stability across a wide range of guitars.
Equipped with a 1:18 gear ratio, the tuning machine provides ultra-precise tuning control and longevity. The construction avoids synthetic polymer coatings to ensure natural acoustic transmission, while permanently locked and sealed screw connections eliminate wear and the need for ongoing maintenance.
Engineered to standard instrument dimensions for straightforward installation and replacement, the tuning machine features countersunk screw holes for solid mounting and optimal tonal transfer.
