Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio that ensures velvet-smooth and exceptionally precise tuning. All components are CNC-machined to exact tolerances, finished to high standards, and utilize a self-locking drive mechanism for stable, sensitive adjustments.
Equipped with high-grade brass string posts engineered precisely into the housing, the M6 Pin guarantees wear-free performance and dependable tuning stability. The stepped M6 flanged washer centers the post reliably via the threaded bushing, eliminating tilting torque and removing the requirement for stepped peghead bore holes.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, this two-pin model shares identical housing dimensions with previous single-pin configurations. It provides a seamless replacement option while delivering optimal string tension handling across various configurations.
