Schaller Machine Head 3×3 Nickel M6-135N-2

The original M6 set a new global standard for closed tuners in 1966. Since 2017, the M6 has offered numerous improvements and innovations without losing its unique aura.

Special features

• Their perfect functionality combined with an improved gear ratio of 1:18 ensures a precise and velvety smooth tuning process.
• All parts are CNC-machined with high precision, surface-finished and guarantee smooth, sensitive and stable tuning thanks to the self-locking drive.
• We manufacture all posts from high-quality brass, they are precisely fitted into the housing and guarantee the highest possible tuning stability and freedom from wear.
• The innovative M6 step-washer guarantees problem-free assembly and permanently solid centering of the post.
• All closed mechanisms are permanently lubricated with Schaller special grease and are therefore absolutely maintenance-free.

Advantages of the M6-step washers

This Schaller innovation facilitates the installation of the M6 machine head and provides additional protection for the perfect function and longevity of your tuning machine head. The additional step at the bottom of the M6 washer (with a diameter of 10 mm) reliably centers the string post via the threaded bushing and eliminates the need for a stepped hole in the headstock. This function eliminates the tilting moment and takes the pressure off both the post and the fixing screw on the back.
