Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines legendary design with advanced precision engineering. Featuring an improved 1:18 gear ratio, it delivers an exceptionally smooth, accurate, and comfortable tuning experience for electric and acoustic guitars.
Every component is high-precision CNC-machined and surface-treated, featuring a self-locking drive and premium brass string posts precisely fitted into the housing for maximum tuning stability and wear resistance. Permanently lubricated with Schaller special grease, the closed housing ensures completely maintenance-free operation.
The innovative stepped M6 flanged washer with a 0.39-inch diameter base centers the string post securely through the threaded bushing. This design eliminates tilting torque, relieves stress from both the post and mounting screw, and removes the need for stepped peghead drilling.
