Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine delivers exceptional tuning precision and stability with an improved 1:18 gear ratio. Designed for smooth, velvet-like action, all components are CNC-machined to exacting tolerances and surface-treated for maximum longevity and wear resistance.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners ensure maintenance-free performance. The self-locking internal drive mechanism provides reliable, fine-touch adjustments without slippage.
Featuring the innovative stepped M6 collar washer with a 0.39 in (10 mm) diameter, this design accurately centers the string post without requiring stepped headstock boreholes. It effectively eliminates tilting torque and reduces structural strain on both the post and mounting hardware.
