Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a benchmark for precision, tuning comfort, and lasting durability. Engineered with a refined 1:18 gear ratio, it provides velvety smooth and accurate tuning stability for modern guitarists. Every component is CNC-machined to exacting standards and surface-finished to ensure seamless operation.
Equipped with high-grade brass string posts precisely fitted into the housing, this machine head offers exceptional wear resistance and zero backlash. The innovative stepped M6 collar washer reliably centers the string post without requiring a stepped headstock bore, eliminating tilting torque and protecting the assembly from excess tension.
Permanently lubricated with specialized Schaller grease, the sealed design remains completely maintenance-free over its lifespan. The rear pin-mount configuration ensures straightforward installation and rock-solid alignment on compatible guitar headstocks.
