Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine delivers precise tuning performance and high tuning stability with an improved 1:18 gear ratio. CNC-machined components and a self-locking drive mechanism ensure smooth, delicate, and consistent operation for demanding guitarists.
Crafted with premium brass string posts precision-fitted into the housing, each machine head offers wear-free operation. The sealed design is permanently lubricated with Schaller special grease for maintenance-free reliability over long-term use.
Featuring the innovative stepped M6 flanged washer, it centers the string post reliably through the banjo bolt without requiring a stepped headstock hole. This design eliminates tilting torque and reduces mechanical strain on both the post and rear mounting screws.
