Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth operation with an improved 1:18 gear ratio. CNC-machined components with a self-locking drive ensure uniform, sensitive, and stable tuning across all instruments.
Equipped with high-grade brass posts precision-fitted into the housing, these enclosed tuners provide wear-free longevity and exceptional tuning stability. All sealed units are permanently lubricated with Schaller special grease for completely maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, each unit eliminates tilt torque and centers the string post securely without requiring stepped headstock drilling. Retaining identical installation dimensions to its predecessor, it serves as a direct, modification-free replacement.
