Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets the standard for enclosed guitar tuners with an advanced 1:18 gear ratio for smooth, precise, and stable tuning performance. CNC-machined components and precision-fitted brass string posts provide exceptional durability, wear resistance, and reliable pitch holding.
Featuring the innovative stepped M6 flanged collar with a 0.39-inch diameter base, this tuner reliably centers the post through the hollow screw without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 Pin delivers flawless long-term reliability. The two-pin mounting layout provides stable positioning with a 0.39-inch center-to-center pin spacing.
