Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune combines vintage-inspired aesthetics with precise tuning performance. Engineered as a classic open-gear tuning machine with a precision worm gear, it delivers ultra-smooth operation and exceptional pitch stability.
Featuring a 1:18 gear ratio, this tuning machine provides meticulous accuracy and lasting durability. The design avoids synthetic coatings to maintain natural acoustic resonance across the instrument headstock, while permanently locked and sealed screw connections ensure maintenance-free, wear-resistant performance.
Crafted to standard serial instrument dimensions for straightforward installation and replacement, each unit includes countersunk screw holes and mounting hardware designed for solid anchoring and optimal tonal transfer.
