Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth operation. Engineered with an upgraded 1:18 gear ratio, it provides exceptionally sensitive and reliable tuning precision for discerning musicians.
Precision CNC-machined components and premium brass posts ensure flawless mechanical fitment, long-term wear resistance, and maximum tuning stability. Each tuner is permanently lubricated with Schaller special grease to remain completely maintenance-free throughout its lifespan.
Equipped with an innovative stepped M6 flanged washer (0.39 in diameter), this tuner centers the string post reliably through the banjonut and eliminates tilting torque without requiring stepped headstock boreholes. It retrofits seamlessly onto standard headstocks for quick and secure installation.
