Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision instrument tuning with an upgraded 1:18 gear ratio for smooth, accurate adjustments. Building upon the legendary closed design introduced in 1966, this modern iteration incorporates state-of-the-art manufacturing to ensure premium tuning stability.
Every component is CNC-machined to precise tolerances and surface-finished for consistent operation. Premium brass string posts are precision-fitted into the housing, while the self-locking drive and permanent lubrication with Schaller special grease ensure maintenance-free, wear-resistant performance.
The innovative stepped M6 flanged washer centers the string post securely via the banjo bolt, eliminating the need for a stepped peghead bore. This advanced design relieves strain from the post and mounting screws to maintain rock-solid alignment.
