Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability. Engineered with a refined 1:18 gear ratio, it delivers ultra-smooth, exact tuning adjustments with self-locking brass drive shafts CNC-machined for zero backlash and wear-free longevity.
Featuring the innovative stepped M6 flanged collar, this machine head self-centers directly through the headstock hole to eliminate tipping torque and stress on mounting hardware. All closed housings are permanently lubricated with Schaller high-grade grease for maintenance-free operation.
Designed with a modern two-pin rear mounting configuration with a 0.4 in (10 mm) pin spacing, the M6 Pin retrofits seamlessly onto standard headstocks while providing rock-solid tuning integrity across diverse playing styles.
