Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its 1:18 gear ratio. Designed with CNC-machined components and high-grade brass posts, it offers velvety smooth and reliable operation for electric and acoustic guitars.
Featuring the innovative stepped M6 flanged washer, this tuner mounts securely while centering the string post directly over the banjo bolt. This eliminates tilting moments and reduces mechanical stress on both the post and rear mounting screw without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease, each closed-housing tuner is completely maintenance-free. Its refined housing design allows for seamless replacement of legacy models without requiring instrument modifications.
