Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for velvety-smooth, precise tuning action. Each component is CNC-machined to exacting tolerances and surface-finished to ensure lasting tuning stability and backlash-free operation.
Equipped with high-grade brass posts fitted seamlessly into the housing, the M6 135 guarantees wear-free performance. The specialized stepped flanged washer centers the string post securely without requiring stepped peghead drilling, eliminating tilting moments and relieving mechanical strain on mounting screws.
Permanently lubricated with Schaller special grease for a fully maintenance-free lifespan, the M6 135 shares identical installation dimensions with its predecessor model, allowing seamless drop-in replacement on electric and acoustic guitars.
