Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a benchmark for closed guitar tuners, combining precision engineering with outstanding tuning stability. Featuring an advanced 1:18 gear ratio, it ensures precise, velvet-smooth tuning and sensitive adjustments.
All components are CNC-machined to tight tolerances, surface-finished, and equipped with a self-locking drive. The high-grade brass string posts are accurately fitted into the housing to guarantee wear-free performance, while permanent factory lubrication with Schaller special grease keeps the mechanism entirely maintenance-free.
An innovative stepped M6 flanged washer centers the string post securely through the hollow screw without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on mounting components.
