Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Continuing the legacy of the original sealed tuner standard established in 1966, this updated design introduces refined precision engineering while maintaining its iconic aesthetic.
Every component is CNC-machined to exact tolerances and surface-finished for lasting durability. Premium brass string posts are fitted precisely into the housing to ensure optimal tuning stability, while the self-locking drive and internal permanent lubrication with special grease provide smooth, maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and solid post centering without requiring stepped headstock holes. This mechanism effectively eliminates tilting torque and relieves pressure from both the post and rear mounting screw.
