Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and exceptional reliability. Featuring an advanced 1:18 gear ratio, it ensures smooth, velvety operation and precise pitch adjustments. High-precision CNC-machined components and high-grade brass string posts provide outstanding structural stability, wear resistance, and long-term durability.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt. This eliminates the need for a stepped peghead hole, prevents tilting torque, and relieves mechanical strain from both the post and rear mounting screws. All sealed housings are permanently lubricated with Schaller special grease for maintenance-free performance.
Designed with a dual-pin configuration at a 0.39 in (10 mm) center-to-center spacing, the M6 Pin offers exact housing compatibility with predecessor models. Complete with banjo bolts, flanged washers, and mounting screws, it provides a secure and stable upgrade for premium guitar headstocks.
