Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for enclosed tuning systems, combining classic heritage with refined modern engineering. Featuring a precise 1:18 gear ratio, it delivers ultra-smooth rotation and outstanding tuning stability for demanding players.
Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation. Solid brass string posts are meticulously fitted into the housing to ensure optimal mechanical alignment and wear-free performance over years of use.
Installation is streamlined thanks to the innovative stepped M6 flanged washer, which reliably centers the string post without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical strain on both the shaft and the rear mounting screws.
