Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin Guitar Tuning Machine delivers exceptional tuning accuracy and smooth operation, building upon the iconic closed-housing tuner design introduced in 1966. Featuring a refined 1:18 gear ratio, this tuning machine provides precise, velvet-smooth adjustment and outstanding tuning stability for solid headstock instruments.
Crafted with precision CNC machining and premium brass string posts, every component is engineered for wear-free performance. The self-locking gear mechanism ensures solid hold under tension, while permanent lubrication with Schaller special grease guarantees completely maintenance-free longevity.
Installation is straightforward and secure thanks to the stepped M6 flanged washer design, which properly centers the string post without requiring stepped headstock drilling. This innovative configuration eliminates tilting torque and relieves mechanical stress from both the post and mounting points.
