Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional tuning precision and stability. Engineered with a refined 1:18 gear ratio, it delivers an ultra-smooth and accurate tuning process. High-precision CNC machining ensures self-locking functionality and long-lasting durability.
Crafted with premium brass string posts fitted directly into the sealed housing, this tuner guarantees high wear resistance and maximum tuning integrity. Permanent internal lubrication with specialized Schaller grease eliminates maintenance requirements entirely.
Featuring the innovative stepped M6 flanged washer, this design centers the string post securely without requiring stepped headstock drilling. This construction absorbs mechanical tilting forces and protects both the string post and rear mounting screw from unnecessary stress.
