Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Continuing the legacy of the original sealed tuner introduced in 1966, this model incorporates modern engineering refinements for outstanding performance.
Precision CNC-machined components and solid brass string posts ensure superior tuning stability, wear resistance, and sensitive adjustments. Sealed housing units are permanently lubricated with Schaller special grease for completely maintenance-free longevity.
An innovative stepped collar washer simplifies installation and reliably centers the post via the threaded bushing without requiring stepped headstock drilling. This design effectively eliminates tilting torque and protects both the string post and rear mounting screws from excess strain.
