Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines legendary design with modern precision, featuring an upgraded 1:18 gear ratio for smooth and ultra-precise tuning performance. Precision CNC-machined components and a self-locking drive mechanism ensure dependable tuning stability and sensitive adjustment.
Crafted with premium high-grade brass string posts engineered for maximum durability and wear resistance, each sealed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation. The stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilt and removing stress from the post and mounting screw without requiring a stepped peghead hole.
Featuring a dual-pin configuration with a 0.39-inch (10 mm) pin spacing and a 0.31-inch (8 mm) distance from pins to string post center, this tuner provides effortless drop-in alignment and robust performance for instrument builders and players seeking uncompromising German engineering.
