Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning accuracy and velvet-smooth operation with its refined 1:18 gear ratio. Engineered with precision CNC-machined components and high-grade brass string posts, it ensures maximum stability, wear resistance, and reliable performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post via the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screw.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 135 shares identical installation dimensions with its predecessor model, allowing seamless drop-in replacement on compatible electric and acoustic guitars.
