Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Designed to set the standard for enclosed tuners, it combines classic heritage with modern engineering innovations.
Precision CNC-machined components and high-grade brass string posts provide outstanding tuning stability, wear resistance, and sensitive adjustment. Permanently lubricated with Schaller special grease, each closed-housing tuner is completely maintenance-free.
The innovative stepped M6 flanged washer ensures effortless mounting and reliable shaft centering via the hollow screw, eliminating the need for stepped headstock holes and removing excess stress from the string post and mounting screw.
