Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-finished, and equipped with a self-locking drive to ensure uniform, sensitive, and stable tuning.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, preventing tipping torque and eliminating the need for a stepped peghead bore.
Each closed machine head is permanently lubricated with Schaller special grease for completely maintenance-free operation. Featuring dual-pin rear mounting with 0.39 in (10 mm) pin spacing, it is engineered for seamless installation and enduring reliability.
