Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers precise and smooth tuning performance with an upgraded 1:18 gear ratio. Designed with high-precision CNC-machined components and surface-treated finishes, it features a self-locking drive mechanism that guarantees consistent tuning stability.
Engineered for enduring reliability, all string posts are manufactured from premium brass and seated precisely within the closed housing. The tuning machine utilizes permanent Schaller special grease lubrication, making the internal assembly completely maintenance-free over its operating life.
Installation is streamlined via the innovative stepped M6 flanged washer, which reliably centers the string post without requiring a stepped headstock bore. The M6 135 maintains the identical installation dimensions of previous models for straightforward, drop-in replacement.
