Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning stability with an improved 1:18 gear ratio. As the modern evolution of the legendary original closed tuner, it features CNC-machined components and a self-locking drive for smooth, consistent operation.
Crafted with premium brass posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and pitch security. It comes permanently lubricated with Schaller special grease, ensuring reliable, maintenance-free performance over years of playing.
The innovative stepped M6 flanged washer centers the string post automatically via the threaded bushing, eliminating tilting torque and making stepped headstock holes unnecessary for straightforward installation.
