Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners with its refined 1:18 gear ratio, delivering precise, velvety-smooth tuning and exceptional pitch stability. Engineered with high-precision CNC-machined parts and a self-locking drive, it provides uniform, sensitive, and dependable performance.
Crafted with premium brass string posts precisely fitted into the housing, these tuners ensure maximum wear resistance. The innovative stepped M6 flanged washer guarantees effortless installation and permanent shaft centering without requiring a stepped peghead bore, eliminating tilting torque and reducing strain on mounting components.
Featuring dual-pin alignment with a 10 mm pin-to-pin center distance, this design ensures a secure hold. Permanently lubricated with Schaller special grease, each enclosed unit remains entirely maintenance-free over its lifespan.
