Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an advanced 1:18 gear ratio, this closed-gear tuner ensures ultra-smooth operation, fine adjustment control, and self-locking drive performance for reliable pitch retention.
Engineered with precision CNC-machined components and premium brass posts, each unit is permanently lubricated with Schaller special grease for maintenance-free longevity. The stepped M6 flanged washer centers the string post securely without requiring stepped peghead drilling, effectively eliminating tilt and minimizing mechanical stress on mounting screws.
Designed to fit modern and vintage instruments seamlessly, the M6 180 serves as a direct, modification-free replacement for classic M6 tuners. Its robust construction and refined engineering provide professional-grade performance and enduring durability for demanding players and luthiers alike.
