Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-type tuners, delivering unmatched tuning accuracy and smooth operation. Engineered with a precise 1:18 gear ratio, this model ensures refined, velvet-smooth adjustments and dependable pitch stability for discerning guitarists.
Every component is precision CNC-machined and surface-finished, featuring a self-locking drive and premium brass string posts carefully fitted into the housing to eliminate wear. The innovative stepped M6 flanged washer effortlessly centers the string post through the hollow screw, removing tilting torque and making stepped headstock drilling obsolete.
Permanently lubricated with Schaller special grease for entirely maintenance-free reliability, the M6 135 shares identical installation dimensions with its predecessor model, allowing seamless drop-in replacement without requiring instrument modifications.
