Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers exceptional tuning accuracy and stability with an improved 1:18 gear ratio. Engineered with high-precision CNC manufacturing and surface finishing, its self-locking drive ensures smooth, precise, and dependable operation.
Equipped with durable brass string posts fitted tightly into the housing, this tuning machine provides maximum wear resistance and consistent performance. The innovative stepped M6 flanged collar reliably centers the string post without requiring a stepped headstock hole, eliminating tilting torque and protecting the assembly.
Permanently lubricated with Schaller special grease, the enclosed housing provides entirely maintenance-free longevity. Designed with a dual-pin configuration at a 10 mm spacing, it integrates cleanly on compatible solid headstocks for professional reliability.
