Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed to set the standard for enclosed tuners, it combines classic engineering with modern refinements for high performance.
Precision CNC-machined components and high-grade brass posts ensure wear-free durability, smooth turning, and maximum tuning stability. Each enclosed tuner is permanently lubricated with proprietary Schaller grease for lifelong, maintenance-free performance.
Featuring the stepped M6 collar washer with a 0.39-inch diameter base, it reliably centers the string post through the banjo bolt without requiring a stepped peghead bore. This advanced design eliminates tilt and relieves pressure from both the post and mounting screws.
