Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for closed tuners with its refined 1:18 gear ratio, delivering exceptional precision and ultra-smooth tuning action. Built with high-precision CNC-machined components and premium surface treatments, it features a self-locking drive to provide consistent, delicate, and ultra-stable string tuning.
Crafted with premium brass posts fitted directly into the housing, this tuning machine delivers exceptional tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged collar with a 0.39-inch diameter base centers the string post via the hollow screw, eliminating tilting torque and reducing mechanical strain without requiring stepped drilling in the headstock.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 retains the identical installation dimensions of previous versions for straightforward drop-in replacement.
