Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin sets a high benchmark for closed tuning machines, featuring a precise 1:18 gear ratio for smooth, accurate, and stable tuning comfort. Each component is CNC-machined to exacting tolerances, surface-finished, and permanently lubricated with Schaller special grease for maintenance-free operation.
Equipped with high-grade brass string posts engineered directly into the housing, this machine head offers superior tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped peghead bore, eliminating tilting torque and reducing strain on mounting screws.
Designed with a modern two-pin mounting configuration, it provides seamless retrofitting onto compatible headstocks while preserving iconic aesthetic appeal. The self-locking internal drive mechanism guarantees consistent performance and sensitive tuning response across all string gauges.
