Schaller M6 Pin Tuning Machine

The Schaller M6 Pin sets an industry benchmark for enclosed tuning machines, combining historic pedigree with modern engineering. Equipped with an advanced 1:18 gear ratio, it delivers ultra-smooth rotation and micro-fine tuning control for exceptional pitch precision.
Precision CNC-machined components and premium brass posts ensure an exact housing fit, high wear resistance, and reliable tuning stability. Each enclosed tuner is permanently lubricated with proprietary Schaller grease, rendering the internal mechanism completely maintenance-free.
The stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating the need for stepped headstock drilling and protecting internal gears from tilting pressure. Integrated dual locating pins allow for clean, screwless mounting.
