Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding tuning precision and smooth operation with its refined 1:18 gear ratio. All components are CNC-machined to exacting tolerances, featuring brass string posts and a self-locking drive mechanism that ensures lasting tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuning machine enables effortless installation and secure shaft centering without requiring a stepped peghead bore. The design effectively eliminates tilting torque while relieving mechanical stress from both the post and the rear mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 Pin incorporates dual locating pins spaced 0.39 in (10 mm) apart. High-precision engineering makes it an ideal replacement or upgrade for modern guitar headstocks.
