Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents precision engineering and refined performance, setting the benchmark for enclosed tuning mechanisms. Featuring an enhanced 1:18 gear ratio, it ensures precise, velvety-smooth tuning adjustments and long-lasting tuning stability for demanding players.
Every component is CNC-machined and surface-treated to exacting tolerances. High-grade brass string posts are precision-fitted into the housing to eliminate wear, while high-grade internal lubrication ensures completely maintenance-free operation over decades of use.
An innovative stepped M6 flanged washer centers the string post directly via the banjo bolt, removing the need for stepped headstock drilling. This design eliminates tilting torque, taking physical pressure off both the string post and rear mounting screws for a seamless upgrade.
