Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for smooth, velvety, and exceptionally precise tuning. Each component is CNC-machined and surface-treated to ensure consistent, sensitive adjustment with long-term mechanical stability.
Equipped with high-grade brass string posts engineered precisely into the housing, these tuners deliver maximum tuning retention and wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the threaded bushing, eliminating tilting torque, reducing strain on rear mounting screws, and removing the need for a stepped headstock bore.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 retains the identical mounting dimensions of its predecessor for drop-in replacement without instrument modification. The set includes threaded bushings, flanged washers, and M2.2 x 9.5 mm mounting screws.
