Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an advanced 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished, featuring high-grade brass string posts engineered for maximum tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation and supports axle centering without requiring a stepped headstock bore. The design eliminates tilting moment while effectively absorbing pressure from both the post and rear mounting screw.
Equipped with permanent internal lubrication via specialized grease, these closed-construction machine heads are completely maintenance-free. They fit seamlessly into standard headstocks as direct replacements for earlier models with uncompromising reliability.
