Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine offers exceptional precision and stability with an upgraded 1:18 gear ratio for smooth, accurate tuning. Building on the legendary enclosed tuner design introduced in 1966, this model features refined engineering, CNC-machined components, and high-grade brass string posts fitted seamlessly into the housing for wear-free performance.
Equipped with an innovative stepped M6 flanged washer, the tuning machine centers the string post securely over the hollow screw without requiring a stepped headstock hole. This design eliminates tilting moment and reduces mechanical stress on both the post and the rear mounting hardware, while factory-sealed permanent grease ensures maintenance-free operation.
Featuring two rear positioning pins with a 0.4 in (10 mm) center-to-center spacing and a 0.3 in (8 mm) post offset, the M6 Pin delivers rock-solid alignment. Its self-locking drive and premium surface finishing guarantee long-lasting tuning stability and velvet-smooth operation across diverse performance environments.
