Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin Guitar Tuning Machine delivers exceptional tuning precision and stability with an improved 1:18 gear ratio. Engineered with CNC-machined components and high-grade brass string posts, it ensures velvet-smooth, reliable, and wear-free operation across various instruments.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the shaft and mounting screws.
Each closed mechanism is permanently lubricated with Schaller special grease for completely maintenance-free performance. Equipped with dual rear locator pins spaced 0.39 in (10 mm) center-to-center, it provides secure anchoring and stable alignment on compatible headstocks.
