Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. CNC-machined components with premium surface finishes ensure smooth, sensitive, and stable tuning performance.
Featuring high-grade brass string posts engineered for wear-free durability, this enclosed tuning machine comes permanently lubricated with Schaller special grease for completely maintenance-free operation.
The stepped M6 flanged washer reliably centers the string post without requiring stepped headstock peg holes, reducing tilt torque and protecting mounting hardware while matching the original installation dimensions for direct replacement.
