Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine sets a high standard for closed guitar tuners, featuring an upgraded 1:18 gear ratio for exceptionally smooth and precise tuning. Each component is CNC-machined to exacting tolerances and treated with a durable surface finish, driven by a self-locking gear design for dependable tuning stability.
Equipped with high-grade brass string posts precision-fitted to the housing, this tuner minimizes wear and maximizes performance. The specialized stepped M6 flanged washer ensures straightforward installation and accurate axis centering without requiring stepped headstock drilling, effectively eliminating tilt and relieving stress on the assembly.
