Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers precise tuning performance and high tuning stability with an improved 1:18 gear ratio. Each component is CNC-machined to tight tolerances, featuring a self-locking drive and permanently lubricated internal mechanics using Schaller special grease for maintenance-free operation.
Equipped with high-grade brass string posts that fit securely into the housing, this machine head prevents wear and ensures optimal string alignment. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilt torque and protecting mounting screws.
Designed with the exact mounting dimensions of previous generation models, the M6 135 allows direct replacement and hassle-free installation on solid or slotted headstocks.
