Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and rock-solid stability. Engineered with a smooth 1:18 gear ratio, this closed-gear tuner features CNC-machined components and a self-locking drive to provide velvet-smooth, highly sensitive operation. Every string post is crafted from premium brass and seated accurately within the housing to eliminate wear and ensure optimal performance.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine simplifies headstock installation while reliably centering the post without requiring a stepped peghead hole. This thoughtful design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting assembly. The enclosed housing is permanently lubricated with Schaller special grease for entirely maintenance-free longevity.
Designed with standard two-pin positioning, the M6 Pin accommodates a wide variety of custom configurations and string post options, including specialized locking systems. Its robust engineering and premium materials guarantee reliable intonation, enhanced resonance, and effortless string changes across diverse playing conditions.
