Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. Designed with closed housing architecture, it builds upon legendary engineering with modern technical enhancements while preserving the model's classic aesthetic.
Every component is CNC-machined to exact tolerances, featuring precision brass posts fitted directly into the housing for maximum tuning stability and wear-free operation. Self-locking drive mechanics and internal permanent grease lubrication ensure seamless, maintenance-free performance over years of play.
Equipped with an innovative stepped flanged washer, the unit centers the string post reliably through the banjonut to eliminate tilt moment without requiring stepped peghead drilling. Direct retrofitting is streamlined with dimensions identical to preceding models for hassle-free installation.
