Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision and tuning comfort with an upgraded 1:18 gear ratio. Designed to improve upon the legendary 1966 closed-housing design, it delivers smooth and consistent performance across a variety of string setups.
Every unit features high-precision CNC-machined components and solid brass string posts that provide rock-solid tuning stability and wear-free operation. The internal mechanism is permanently lubricated with Schaller special grease for completely maintenance-free functionality.
Equipped with an innovative stepped flanged washer, this tuning machine centers the string post securely without requiring stepped peghead drilling. It matches the standard installation footprint of previous models for straightforward, drop-in replacement.
