Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and comfort with an upgraded 1:18 gear ratio. Designed to match the exact mounting dimensions of its historic predecessor, it allows for seamless replacement without headstock modifications.
Every component is CNC-machined and surface-treated for refined performance, utilizing high-grade brass posts fitted tightly into the housing to ensure maximum tuning stability and wear resistance. The sealed design comes permanently lubricated with Schaller special grease for completely maintenance-free operation.
Featuring an innovative stepped flanged washer, this tuning machine centers the string post securely through the banjo bolt without requiring a stepped headstock bore. This structure effectively eliminates tilting torque and reduces mechanical strain on both the post and mounting screw.
