Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and velvety smooth operation thanks to its refined 1:18 gear ratio. Continuing the legacy of the original 1966 closed-type tuner, this modernized edition incorporates precision CNC-machined components and premium surface finishing for uniform, sensitive, and wear-free stability.
Crafted with precision-fitted brass string posts, this tuning machine features a self-locking drive and permanent lubrication with Schaller special grease, making it completely maintenance-free. The innovative stepped M6 flanged washer centers the string post securely over the banjo bolt, eliminating tilt and removing mechanical pressure from both the post and mounting screw without requiring a stepped headstock bore.
Engineered for direct replacement without instrument modification, the M6 180 provides unmatched reliability for players demanding stable intonation and flawless tuning performance.
