Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine represents an advanced evolution of the legendary sealed tuner design that set global industry standards in 1966. Engineered with a refined 1:18 gear ratio, this machine head delivers exceptional tuning accuracy, velvet-smooth rotation, and dependable performance across demanding playing styles.
Every component is precision CNC-machined and surface-treated for maximum durability, featuring self-locking gearing to ensure rock-solid pitch stability. The high-grade brass string posts fit precisely within the housing to eliminate play and wear, while permanent internal lubrication with specialized grease guarantees maintenance-free operation for years to come.
An innovative stepped M6 flanged washer simplifies headstock installation by self-centering the string post through the banjonut, eliminating the need for stepped headstock reaming. This design absorbs mechanical pressure and tilt torque from both the string post and rear mounting screw, safeguarding your instrument and ensuring effortless mounting.
