Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. CNC-machined components with a self-locking drive ensure velvet-smooth, highly consistent, and stable tuning performance across all string tensions.
Crafted with premium brass string posts precision-fitted into the housing, this closed tuning machine offers maximum wear resistance and tuning stability. Each unit is permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring the innovative stepped M6 flanged washer with a 0.39 in (10 mm) base diameter, the post is securely centered without requiring a stepped headstock hole. This design eliminates tilting torque and reduces physical stress on both the post and mounting hardware.
