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. Designed as an evolution of the legendary original sealed tuner first introduced in 1966, this model incorporates refined mechanics and high-grade construction without compromising its iconic heritage.
Each component is CNC-machined with high precision and surface-treated for maximum durability, paired with solid brass string posts that provide wear-free stability. The self-locking drive mechanism ensures sensitive, consistent, and backlash-free tuning, while factory lubrication with Schaller special grease guarantees permanently maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuner aligns the post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and relieves mechanical stress on both the string post and rear mounting screws for a reliable, modification-free fit.
