Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. As an evolution of the legendary original sealed tuning machine first released in 1966, this model incorporates refined mechanical enhancements while maintaining its classic design.
Precision CNC-machined components and high-grade brass string posts ensure superior tuning stability, wear resistance, and smooth performance. The self-locking drive and high-precision fitting prevent unwanted backlash and slipping during adjustment.
Each unit features the stepped M6 flanged washer, which centers the string post securely without requiring a stepped headstock hole. Permanently lubricated with specialized Schaller grease, these enclosed tuning machines remain completely maintenance-free over years of reliable use.
