Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers precise tuning and exceptional comfort with an advanced 1:18 gear ratio. Designed to preserve the legendary heritage of the original enclosed tuner, this model offers refined mechanics engineered for effortless and velvety-smooth adjustment.
Every component is precision CNC-machined and surface-treated, featuring high-grade brass posts engineered for wear-free durability and maximum tuning stability. The self-locking drive mechanism provides consistent, sensitive response, while factory-sealed lifetime lubrication ensures completely maintenance-free operation.
Equipped with an innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring stepped headstock drilling. It maintains identical installation dimensions to its predecessor for direct replacement and eliminates tilting torque while relieving pressure on both the post and rear mounting screws.
