Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. Designed with the identical mounting dimensions of its predecessor, it allows for direct and modification-free replacement on compatible headstocks.
Every component is CNC-machined and surface-finished to high tolerances, paired with high-grade brass string posts engineered for maximum tuning stability and wear resistance. Closed housings are permanently lubricated with proprietary Schaller grease, providing lifetime maintenance-free performance.
Featuring the innovative stepped M6 flanged washer with a 0.39 in diameter base, this tuning machine automatically centers the string post via the hollow bolt. This design eliminates tilting torque and protects both the post and rear mounting screws from excess pressure.
