Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and velvet-smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original closed-type machine head introduced in 1966, this updated design incorporates modern manufacturing enhancements for maximum performance.
Each component is CNC-machined to precise tolerances and surface-finished, featuring high-grade brass posts fitted tightly into the housing for wear-free stability. The self-locking drive and permanently lubricated internal mechanism ensure maintenance-free, uniform response across every string change.
Equipped with Schaller's stepped flanged washer, the unit centers securely without requiring stepped headstock boreholes. This engineered fit eliminates tilting torque and protects both the post and rear mounting screw from unnecessary strain.
