Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision and tuning stability. Engineered with an improved 1:18 gear ratio, it ensures smooth, velvety operation and precise tuning adjustments. Every component is CNC-machined and surface-treated for flawless mechanical performance and long-lasting durability.
Featuring high-grade brass posts fitted accurately into the housing, this enclosed tuner guarantees exceptional wear resistance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilting moment and relieving pressure from both the post and rear mounting screw without requiring stepped peghead drilling.
Permanently lubricated with Schaller special grease for maintenance-free service, the M6 135 shares identical installation dimensions with its predecessor model, allowing seamless drop-in replacement without instrument modifications.
