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 CNC-machined and surface-treated, featuring a self-locking drive mechanism and premium brass string posts fitted directly into the housing to prevent wear and ensure lasting accuracy.
Equipped with Schaller's innovative stepped flanged washer, this tuner allows straightforward mounting and permanent axis centering without requiring a stepped headstock bore. The design eliminates tilting moments and relieves tension from both the string post and the rear mounting screw.
Featuring permanently lubricated internal components with specialized grease, the enclosed housing remains entirely maintenance-free over its service life. The M6 135 retains the exact installation dimensions of its predecessor for seamless drop-in replacement on compatible headstocks.
