Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and reliability, featuring an upgraded 1:18 gear ratio for smooth, velvety tuning and precise intonation adjustments. Every component is CNC-machined to exacting tolerances and coated with high-grade surface finishes, while the brass posts are carefully seated within the closed housing to eliminate play and ensure long-term tuning stability.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine centers the string post securely over the threaded bushing, eliminating tilting torque and reducing strain on both the post and mounting hardware without requiring step-drilled peghead holes. Permanent internal lubrication with specialized Schaller grease ensures entirely maintenance-free operation under rigorous playing conditions.
Engineered for effortless pin-mount installation, the dual-pin configuration provides a rock-solid mechanical anchor with a standardized 0.39 in (10 mm) pin spacing and a 0.31 in (8 mm) spacing from the pins to the center of the post. This professional-grade machine head delivers unmatched durability, wear resistance, and tuning accuracy for discerning musicians and custom instrument builders.
