Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Continuing the legacy of the original sealed tuner standard set in 1966, this model features high-precision CNC-machined components and self-locking drive mechanics for stable, sensitive adjustment.
Crafted with premium brass string posts fitted precisely into the housing, each unit ensures maximum tuning stability and wear-free performance. The specialized step washer facilitates straightforward installation and reliable post centering without requiring a stepped headstock hole.
Permanently lubricated with Schaller special grease, these sealed tuners operate completely maintenance-free. Designed for versatile compatibility, they fit standard headstock setups and can replace predecessor units directly without modifications.
