Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and smooth operation with an improved 1:18 gear ratio. Each component is CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees consistent, highly responsive, and reliable tuning stability.
Equipped with premium brass string posts precision-fitted into the housing, this closed machine head ensures maximum durability and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing pressure on mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free performance, the M6 Pin features a 0.39 in center-to-center pin distance. It comes complete with threaded bushings, step washers, and mounting screws for straightforward installation on compatible instruments.
