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. Designed as an evolution of the iconic original sealed tuner, it features CNC-machined components and self-locking drive mechanisms to ensure long-lasting stability.
Equipped with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and pitch stability. The innovative stepped M6 flanged washer centers the string post securely over the threaded bushing, eliminating tilting torque and protecting the headstock.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. They are engineered to replace previous M6 models without headstock modifications, providing seamless installation and modern performance for fine instruments.
