Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. CNC-machined from premium materials, each component ensures smooth, consistent, and wear-free operation with a self-locking drive and high-grade brass posts.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation while eliminating tilting torque and reducing pressure on the string post and rear fixing screw. The stepped design reliably centers the post without requiring a stepped headstock hole.
All closed-type housings are permanently lubricated with Schaller special grease for entirely maintenance-free performance. Available in a wide variety of configurations, finishes, button materials, and post types to match your exact instrument specifications.
