Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine offers precision engineering and smooth tuning stability with an advanced 1:18 gear ratio. All components are CNC-machined to exacting tolerances, featuring self-locking brass posts and wear-free operation sealed with permanent lubrication.
Featuring the innovative stepped M6 flanged collar, this design self-centers the string post securely through the banjo bolt without requiring stepped headstock holes, eliminating tilt torque and protecting against excessive mechanical stress.
Equipped with a dual-pin configuration set at a 10 mm center-to-center distance, these sealed tuners match the housing footprint of classic models while delivering reliable hold and effortless intonation adjustments.
