Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. Designed to build upon the legendary closed-housing platform established in 1966, this model incorporates refined mechanical innovations for maximum reliability.
Each unit features precision CNC-machined components with premium surface finishing and self-locking drive mechanics for consistent tuning stability. The high-grade brass string posts are meticulously fitted into the housing, ensuring long-term wear resistance and flawless performance.
An innovative stepped M6 flange washer with a 0.39-inch diameter simplifies installation and solidly centers the string post without requiring stepped headstock drilling. Permanently lubricated with Schaller special grease, these sealed tuners provide completely maintenance-free functionality.
