Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides exceptional tuning accuracy and smooth operation. Designed with precision CNC-machined components and surface-finished parts, it utilizes a self-locking drive to ensure consistent and highly stable tuning.
Crafted with premium brass string posts fitted precisely into the housing, this tuning machine delivers superior wear resistance and maximum pitch stability. The stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing mechanical stress.
Each enclosed unit is permanently lubricated with Schaller special grease for completely maintenance-free performance. Engineered for straightforward installation, the two-pin configuration maintains standard housing dimensions for reliable retrofitting and enduring durability.
