Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune combines refined vintage styling with precise tuning response and ultra-smooth operation. Designed as an open-gear tuner with an exposed worm and gear mechanism, it provides an authentic classic appearance alongside state-of-the-art engineering.
Equipped with an 18:1 gear ratio, this machine head offers exceptional tuning accuracy and longevity. The absence of synthetic coatings ensures maximum resonance transmission across the instrument, creating a wear-resistant assembly built to last.
Engineered to standard instrument dimensions for straightforward installation and replacement, it features permanently locked and sealed screw connections along with countersunk mounting holes for a secure fit and optimal acoustic coupling.
