Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin series sets the standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio that ensures ultra-smooth tuning and maximum stability. Each component is high-precision CNC-machined with a premium surface finish and equipped with a self-locking drive mechanism for consistent, sensitive adjustments.
Crafted with premium brass string posts fitted accurately into the housing, these tuners offer exceptional wear resistance and long-term tuning stability. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tipping torque and preventing stress on both the post and rear mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 Pin utilizes a two-pin rear mounting configuration with a 0.39-inch center-to-center spacing. This versatile design offers effortless installation on solid headstocks while delivering legendary reliability and performance.
