Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and premium brass posts, it ensures wear-free operation and consistent performance.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and self-centering of the string post via the banjo bolt. This specialized design eliminates tilt torque and relieves mechanical stress from both the post and the rear mounting screw without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease for maintenance-free reliability, the M6 135 retains the exact mounting dimensions of its classic predecessor for straightforward replacement and upgrades.
