Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and smooth tuning stability with an improved 1:18 gear ratio. All components are high-precision CNC-machined and surface-treated, featuring a self-locking drive mechanism that ensures delicate and consistent tuning.
Equipped with high-grade brass string posts engineered precisely into the housing, this tuning machine delivers wear-free performance and superior tuning retention. The innovative stepped M6 flanged washer centers the string post through the banjo bolt, eliminating the need for a stepped peghead hole while removing tilting torque and stress from mounting screws.
Featuring permanent internal lubrication with specialized grease, each sealed tuner requires zero maintenance throughout its lifespan. Designed with identical installation dimensions to its predecessor, it serves as a seamless drop-in replacement without requiring guitar modifications.
