Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-treated, and utilize a self-locking drive mechanism to provide smooth, sensitive, and reliable tuning stability.
Equipped with high-grade brass string posts precisely fitted into the housing, the M6 135 guarantees wear-free performance and exceptional longevity. The innovative stepped M6 flanged washer centers the string post reliably through the banion screw, eliminating tilting torque and protecting the headstock without requiring stepped drilling.
Featuring permanent lubrication with Schaller special grease, these sealed tuners are completely maintenance-free. Designed with identical mounting dimensions to its classic predecessor, the M6 135 serves as a direct drop-in replacement without requiring guitar modifications.
