Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning stability, featuring an improved 1:18 gear ratio for smooth, accurate adjustments. Building upon the legendary sealed tuner design first introduced in 1966, this modern version delivers premium performance across a wide range of instrument setups.
Every component is precision CNC-machined and surface-finished, featuring high-grade brass posts fitted seamlessly into the housing. The self-locking drive and permanent lubrication with specialized grease ensure maintenance-free operation, wear resistance, and long-lasting reliability.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by automatically centering the string post via the banjo bolt. This eliminates tilting moment, relieves pressure on mounting screws, and shares identical footprint dimensions with predecessor models for seamless replacement.
