Schaller GrandTune Single Guitar Tuning Machine
The Schaller GrandTune Single combines refined vintage aesthetics with precise tuning response and smooth operation. Engineered with an open gear and worm drive mechanism, it delivers exceptional tonal resonance across acoustic and electric instruments without the use of synthetic coatings.
Featuring an 1:18 gear ratio, this machine head provides pinpoint tuning precision and long-lasting stability. Ultra-precise contact surfaces offer optimal stick-slip performance without polymer coatings, while permanently locked and sealed screw joints ensure wear-free and maintenance-free reliability.
Designed around standard production instrument dimensions, the GrandTune allows for straightforward installation and replacement. Countersunk screw holes ensure secure mounting and optimal acoustic coupling between the tuner and the instrument headstock.
