Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and comfort with an advanced 1:18 gear ratio. Designed with CNC-machined components and a self-locking drive, it ensures smooth, consistent, and exceptionally stable tuning performance.
Crafted with premium brass string posts precision-fitted into the housing, each unit offers maximum wear resistance and tuning reliability. Permanent lubrication with Schaller special grease ensures completely maintenance-free operation over its entire lifespan.
An innovative stepped M6 flanged washer centers the string post reliably without requiring a stepped peghead bore, eliminating tilting torque and reducing mechanical stress on the post and mounting points.
