Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision, tuning comfort, and lasting durability. Engineered with a refined 1:18 gear ratio, it ensures exceptionally smooth, precise, and stable tuning performance for electric and acoustic guitars.
Every component is CNC-machined to precise tolerances and surface-finished for premium wear resistance. The high-grade brass string posts fit securely into the housing, while the self-locking drive and internal permanent lubrication with Schaller special grease ensure maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring stepped headstock drilling. It maintains standard mounting dimensions for seamless replacement and eliminates tilting torque on the mounting hardware.
