Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuning machines, combining timeless design with modern precision engineering. Built with a refined 1:18 gear ratio, it delivers velvety-smooth action, exact adjustments, and exceptional tuning stability.
Every component is precision CNC-machined and surface-finished to ensure seamless operation. The high-grade brass posts fit precisely into the housing to prevent wear, while the self-locking drive and Schaller permanent lubrication grease provide completely maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuner aligns reliably without requiring stepped peghead drilling. This design eliminates tilting moments and relieves tension from both the string post and rear fixing pins.
