Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Designed with high-precision CNC-machined components and surface-finished parts, it utilizes a self-locking drive mechanism to provide smooth, sensitive, and dependable tuning stability across all playing conditions.
Engineered for enduring performance, every post is crafted from premium brass and seated precisely within the sealed housing. All enclosed tuners come permanently lubricated with Schaller special grease, ensuring completely maintenance-free operation and eliminating internal wear over time.
Featuring the innovative stepped M6 flanged collar, this tuning machine enables effortless installation while centering the string post directly through the banjo bolt. This eliminates the need for stepped headstock drilling, cancels out tilting torque, and relieves physical pressure from both the post and rear mounting points.
