Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers state-of-the-art precision and smooth tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, it provides maximum tuning stability and wear-free performance.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and relieves mechanical stress on both the post and the rear mounting screw.
Featuring permanent internal lubrication with special Schaller grease, all enclosed mechanisms are completely maintenance-free. The M6 135 maintains the exact mounting dimensions of its predecessor for effortless, drop-in replacement on compatible guitar headstocks.
