Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuners, combining precision German engineering with refined functionality. Built with high-precision CNC-machined components and a self-locking drive, it delivers exceptionally smooth and reliable tuning. A premium 1:18 gear ratio ensures fine-tuned accuracy, while the high-grade brass posts fit seamlessly into the housing for maximum stability and wear resistance.
Featuring the innovative M6 stepped collar washer with a 0.39-inch (10 mm) diameter, this tuner eliminates the need for stepped headstock holes by reliably centering the string post directly via the banjo bolt. This design absorbs lateral tilt force and reduces stress on both the string post and rear mounting screws. Every enclosed tuner is permanently lubricated with Schaller special grease for maintenance-free operation over its entire lifespan.
Equipped with a dual-pin configuration with a 0.39-inch (10 mm) pin spacing and an 0.31-inch (8 mm) spacing from the pin to the center of the post, the M6 Pin offers exact housing dimensions for seamless upgrades. Suitable for a wide range of headstock configurations, it delivers robust performance and rock-solid intonation for serious musicians and custom builders.
