Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. Designed to replace previous generations without headstock modification, it features high-grade CNC-machined components and solid brass posts fitted directly into the housing.
Equipped with Schaller's stepped flanged washer, this machine head centers the string post securely over the hollow screw, eliminating tilt torque and protecting against excessive friction. Each unit is permanently lubricated with specialized Schaller grease to deliver maintenance-free operation over its lifespan.
Constructed with durable materials and refined finishes, these tuning machines provide exact intonation and dependable holding power for demanding players. Mounting hardware including banjos, stepped washers, and M2.2 x 9.5 mm attachment screws are supplied for standard installations.
