Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuning systems, combining classic design with contemporary German engineering. Featuring an improved 1:18 gear ratio, it delivers ultra-precise, velvety-smooth tuning response and lasting stability across demanding performance environments.
Every component is CNC-machined to exact tolerances and surface-finished for premium wear resistance. The high-grade brass string posts are precisely fitted into the housing, while self-locking drive mechanics and permanent internal lubrication with Schaller specialized grease ensure completely maintenance-free operation.
An innovative stepped M6 flanged collar simplifies headstock installation by securely centering the string post via the banjo bolt. This specialized design eliminates tilting torque and disperses tension away from both the post and rear mounting screws, ensuring reliable centering and lasting structural integrity.
