Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original closed-type tuner introduced in 1966, this model incorporates refined mechanical innovations for modern guitarists.
Every component is CNC-machined to precise tolerances and finished for smooth, self-locking operation and exceptional tuning stability. High-grade brass string posts fit securely into the housing, ensuring wear-free longevity, while permanently lubricated internal gears with Schaller special grease ensure maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuner allows straightforward mounting without the need for a stepped headstock bore. The stepped design reliably centers the string post and eliminates tilting torque, relieving pressure from both the post and mounting screw.
