Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuning mechanisms, featuring a refined 1:18 gear ratio that delivers exceptional precision, smooth operation, and tuning stability. Each component is CNC-machined to precise tolerances and finished to ensure velvet-smooth, self-locking drive performance without gear slip.
Equipped with high-grade brass string posts engineered for wear resistance, the M6 Pin incorporates an innovative stepped flanged washer with a 0.39 in (10 mm) base. This design centers the string post securely through the banjo bolt, eliminating tilting moment and relieving stress on both the post and rear mounting screws without requiring stepped headstock drilling.
Permanently lubricated with specialized Schaller grease for maintenance-free longevity, these 2-pin tuners share identical housing dimensions with previous single-pin configurations with a 0.39 in (10 mm) pin-to-pin center distance. Included hardware consists of six banjo bolts, six flanged washers, and six M2.2 x 9.5 mm mounting screws.
