Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined and finished with extreme precision, featuring a self-locking drive mechanism that ensures consistent, responsive, and stable tuning performance.
Crafted with premium brass string posts precisely fitted into the housing, these enclosed tuners offer maximum tuning stability and wear-free operation. The innovative stepped M6 flanged washer centers the string post securely via the banjo bolt, eliminating tipping torque without requiring a counterbore in the headstock.
Permanently lubricated with Schaller special grease for maintenance-free reliability, the M6 135 shares the exact installation dimensions of its predecessor for effortless, modification-free replacement on existing instruments.
