Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances, high-grade surface finished, and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring high-grade brass string posts engineered into a durable closed housing, these tuners ensure maximum tuning stability and wear-free performance. The self-locking drive maintains steady tension, providing a reliable and sensitive feel during every adjustment.
An innovative stepped M6 flanged washer (0.39 in diameter) securely centers the string post without requiring a counterbore in the headstock. This smart design eliminates tilting torque and relieves pressure from both the post and the rear mounting fixture.
