Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision engineering with an improved 1:18 gear ratio, delivering smooth, accurate, and stable tuning performance. All internal components are CNC-machined and surface-treated, featuring a self-locking drive and high-grade brass posts precisely fitted into the housing for exceptional wear resistance and long-lasting stability.
Featuring Schaller's innovative stepped flanged washer, this tuner simplifies installation while securely centering the string post via the banjo bolt. This eliminates the need for a stepped peghead hole, prevents tilting torque, and relieves stress on both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 matches the exact mounting dimensions of its predecessor for hassle-free drop-in replacement without instrument modifications.
