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. Each component is CNC-machined and surface-treated to guarantee smooth, delicate, and stable tuning performance with a self-locking drive.
Crafted with premium brass string posts precisely fitted into the housing, these tuners ensure maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock hole, eliminating tilting torque and reducing pressure on the post and rear fixing screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, this two-pin model shares the identical housing dimensions of its single-pin predecessor with a 10 mm (0.39 in) center-to-center pin spacing.
