Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 represents an advanced evolution of the legendary enclosed guitar tuning machine, engineered with a refined 1:18 gear ratio for exceptionally smooth and precise tuning accuracy. Every component is CNC-machined to exact tolerances and surface-treated to guarantee consistent, wear-free performance and superior tuning stability over extended play.
Featuring premium brass string posts precisely seated within the housing, the M6 135 delivers rock-solid performance with virtually zero backlash. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing, eliminating tilting movement, relieving pressure on the mounting screws, and removing the need for a stepped peghead bore.
Permanently lubricated with specialized Schaller grease for entirely maintenance-free operation, this tuner shares identical mounting dimensions with its predecessor model for seamless drop-in replacement. Configured with a durable finish, precision internal drive, and premium buttons, it delivers unmatched tuning stability for demanding musicians.
