Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning stability with an improved 1:18 gear ratio. Each component is CNC-machined to precise tolerances and finished for smooth, velvet-like operation and dependable tuning performance.
Equipped with high-grade brass string posts that fit securely into the housing, this tuning machine provides maximum wear resistance and pitch consistency. The permanently lubricated, sealed housing utilizes Schaller special grease to remain completely maintenance-free over its entire service life.
Featuring the innovative stepped M6 flanged washer, this tuning machine centers the string post securely without requiring stepped peghead holes. This smart design eliminates tilting moments and relieves mechanical stress from both the post and the rear mounting screw.
