Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuning mechanisms, featuring a precise 1:18 gear ratio for smooth and accurate tuning stability. Built with high-precision CNC-machined components and high-grade brass string posts fitted directly into the housing, it ensures wear-free operation and exceptional durability.
Featuring the innovative M6 stepped flanged washer, this tuning machine simplifies installation while reliably centering the string post via the banjo bolt. This specialized design eliminates tilting torque and takes mechanical strain off both the post and the rear mounting screw, removing the need for a stepped peghead bore.
All enclosed gear housings are permanently lubricated with Schaller special grease for completely maintenance-free performance. Designed with the identical footprint and mounting dimensions of its predecessor, the M6 135 offers a seamless, drop-in replacement for effortless instrument upgrades.
