Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines stylish vintage design with precise tuning response and smooth performance. This classic open-gear tuning machine features an exposed worm gear and precise construction engineered for lasting reliability.
A 1:18 gear ratio delivers exact tuning control and velvet-smooth operation. Manufactured without synthetic coatings, the tuning mechanism allows natural acoustic resonance while ultra-precise fittings ensure stick-slip-free movement without premature wear or aging.
Permanently locked and sealed screw joints provide maintenance-free durability over extended use. Standard instrument dimensions and countersunk screw holes ensure seamless installation, solid anchoring, and optimal acoustic transfer.
