Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers refined tuning precision and exceptional stability with an advanced 1:18 gear ratio. Designed as an evolution of the iconic closed tuning machine, it features high-precision CNC-machined components and a self-locking drive mechanism for ultra-smooth and reliable operation.
Crafted with premium brass string posts precisely fitted into the housing, the M6 180 ensures maximum wear resistance and superior tuning integrity. The innovative stepped M6 flanged washer centers the string post securely through the banjonut, eliminating tilting moments and removing stress from the post and mounting screw without requiring a stepped peghead hole.
Permanently lubricated with Schaller special grease, each enclosed tuner provides completely maintenance-free performance. The slightly compact housing dimensions allow for direct replacement of predecessor models without modifications, making it a dependable choice for premium guitar builds and upgrades.
