Each component is CNC-machined to exacting tolerances and equipped with self-locking drive mechanisms to ensure reliable, non-slip performance.
Equipped with high-grade brass string posts engineered for wear-free operation, these tuners utilize the innovative stepped M6 flanged washer for reliable post centering without requiring a stepped headstock bore. Permanent internal lubrication with Schaller specialty grease ensures completely maintenance-free functionality over extended use.
Designed with a 2-pin mounting layout featuring 0.39-inch pin spacing, these tuning machines provide a secure fit and eliminate tipping moment. Included in the set are matching threaded bushings, stepped washers, and mounting screws for complete installation.
