Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets the benchmark for closed guitar tuning machines with an upgraded 1:18 gear ratio for smooth, high-precision tuning. Every component is CNC-machined with high accuracy and finished to provide sensitive, stable tuning backed by a self-locking drive mechanism.
Equipped with high-grade brass string posts engineered into the housing, these tuners deliver long-term wear resistance and superior tuning stability. The closed design features permanent lubrication with Schaller special grease for maintenance-free operation across years of play.
An innovative stepped collar washer centers the string post securely over the threaded bushing, eliminating the need for a stepped peghead bore while removing lateral pressure from both the post and mounting screw.
