Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, combining legendary heritage with modern engineering. Built with high-precision CNC-machined components and a refined 1:18 gear ratio, it provides velvety smooth operation, exceptional tuning comfort, and reliable self-locking stability.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine delivers maximum wear resistance and pitch stability. All enclosed mechanisms are permanently lubricated with Schaller special grease, ensuring maintenance-free performance throughout their lifespan.
Featuring the innovative stepped M6 flanged washer with a 0.39 in diameter base, installation is effortless and eliminates the need for stepped headstock drilling. This smart design centers the string post securely through the banjonut, eliminating tilting torque and protecting both the post and mounting screws from strain.
