Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with a refined 1:18 gear ratio, delivering velvet-smooth operation and unmatched tuning stability. Every component is CNC-machined to exacting tolerances and surface-finished, featuring a self-locking drive mechanism for even, sensitive, and reliable adjustments.
Crafted from premium brass, the string posts fit snugly into the housing to guarantee maximum wear resistance and long-lasting performance. An innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilting moment and relieving mechanical stress from both the post and mounting screw without requiring a stepped headstock bore.
Each closed-type tuning machine is permanently lubricated with proprietary Schaller special grease, rendering it completely maintenance-free. Designed for direct drop-in replacement of predecessor models, the M6 180 seamlessly upgrades your instrument with world-class German craftsmanship.
