Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machines deliver exceptional precision and smooth tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original 1966 closed-gear design, these machine heads incorporate modern refinements while preserving classic aesthetic appeal.
Precision CNC-machined components and high-grade brass string posts provide smooth operation, reliable self-locking performance, and long-term tuning stability. Each closed tuning machine is permanently lubricated with Schaller special grease for maintenance-free durability.
Equipped with an innovative stepped flanged washer with a 0.4 in (10 mm) diameter base, these tuners reliably center the post via the banjonut without requiring stepped drilling in the headstock. This mechanism eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
