Schaller GrandTune Guitar Tuning Machine
The Schaller GrandTune represents the ultimate fusion of stylish vintage design, precise tuning accuracy, and velvet-smooth performance. This perfected classic open-gear tuning machine features an exposed gear and worm drive mechanism engineered to exacting standards.
Its 1:18 gear ratio provides unsurpassed precision and long-lasting performance. The deliberate omission of synthetic coatings creates a perfectly resonating component for your instrument, allowing pure tone transfer and exceptional acoustic resonance.
Equipped with ultra-precise contact surfaces and permanently locked, sealed screw joints, the GrandTune delivers maintenance-free, wear-resistant reliability. Designed around standard instrument dimensions, it enables straightforward installation and replacement on fine guitars.
