Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners with an advanced 1:18 gear ratio that provides precise, velvety-smooth, and reliable tuning stability. Every component is CNC-machined to exact tolerances, featuring brass string posts precision-fitted into durable housings with a self-locking drive mechanism for wear-free performance.
An innovative stepped M6 flanged washer ensures effortless mounting and centered post alignment without requiring stepped headstock drilling, effectively eliminating tilt torque and taking pressure off the mounting screws. All enclosed tuners come permanently lubricated with specialized Schaller grease for lifelong, maintenance-free operation.
Designed with dimensions identical to its classic predecessor, the M6 135 allows direct drop-in replacement on compatible headstocks without body or woodwork modifications. This legendary tuning machine delivers uncompromising tuning comfort, exceptional build quality, and unmatched acoustic instrument stability.
