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. Continuing the legacy of the original 1966 closed-housing design, this updated iteration features CNC-machined components and premium brass posts that guarantee smooth, velvet-like operation and long-lasting tuning stability.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the hollow bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear fastening pins.
Each unit is permanently lubricated with Schaller special grease, ensuring completely maintenance-free performance. Designed with self-locking drive mechanics and a 0.39 in (10 mm) pin spacing, the M6 Pin provides rock-solid reliability for demanding players and instrument builders.
