Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and tuning comfort with a refined 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, it ensures smooth operation, precise adjustment, and long-lasting tuning stability.
Featuring the innovative stepped M6 flanged washer, this tuner allows hassle-free installation and permanent center alignment of the string post via the hollow screw, eliminating tilting torque without requiring stepped drilling in the headstock.
Each enclosed tuning machine is permanently lubricated with Schaller special grease for maintenance-free performance and shares the identical installation dimensions of its predecessor for seamless replacement.
