Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning precision and velvet-smooth operation with its refined 1:18 gear ratio. All components are CNC-machined with high precision, surface-finished, and permanently lubricated with Schaller special grease for maintenance-free reliability.
Featuring high-grade brass string posts precisely fitted into the housing, this closed tuning machine ensures maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post reliably via the threaded bushing, eliminating tilting torque and protecting both the shaft and mounting screw without requiring stepped peghead drilling.
Designed with identical installation dimensions to its predecessor, the M6 135 allows direct replacement without instrument modification. The set includes threaded bushings, stepped flanged washers, and M2.2 x 9.5 mounting screws for straightforward installation.
