Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets a benchmark for closed guitar tuning machines, offering an upgraded 1:18 gear ratio for exceptionally precise, smooth, and comfortable tuning. Engineered with high-precision CNC machining and high-grade brass string posts, these machine heads ensure superior wear resistance and long-term tuning stability.
Featuring the innovative stepped M6 flanged washer, this system eliminates tilting moments and absorbs tension directly from both the string post and rear fixing, ensuring effortless installation without requiring a stepped peghead bore. Every tuner is permanently lubricated with specialized Schaller grease to deliver completely maintenance-free performance.
Designed to fit modern headstocks with a 10 mm pin spacing, these tuning machines provide a seamless upgrade or replacement. With self-locking drives and durable internal gearing, they deliver consistent, sensitive, and reliable string tension under any playing conditions.
