Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. As the modern evolution of the legendary original closed tuner introduced in 1966, it features state-of-the-art CNC machining and high-grade surface finishing for enduring reliability.
Equipped with solid brass posts precisely fitted into the housing, this machine head guarantees maximum tuning stability and wear-free performance. The self-locking drive and internal permanent lubrication with Schaller special grease ensure maintenance-free operation across years of regular playing.
Installation is straightforward thanks to the innovative stepped M6 flanged washer, which centers the string post securely without requiring a counterbore in the headstock. This design effectively eliminates tilting torque while relieving stress from both the post and rear mounting screws.
