Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark with its advanced 1:18 gear ratio, delivering precise and velvety-smooth tuning stability. Every component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free operation and exceptional durability.
Featuring premium solid brass posts precision-fitted to the housing, this closed tuner minimizes backlash and wear. The innovative stepped M6 flanged washer reliably centers the string post via the threaded bushing, eliminating the need for a stepped peghead bore and removing side-load strain from both the post and mounting points.
Designed for easy installation with a dual-pin configuration, the M6 Pin offers solid anchoring without compromising the classic aesthetic. High-grade materials and fine craftsmanship ensure outstanding tuning accuracy and long-lasting mechanical reliability across all instrument types.
