Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine continues a legendary standard in precision tuning with an upgraded 1:18 gear ratio for exceptionally smooth and reliable operation. Every component is CNC-machined to exacting tolerances, featuring brass posts meticulously fitted into the housing to ensure long-term tuning stability and wear-free performance.
Equipped with an innovative stepped M6 flanged washer, this machine head simplifies headstock installation by reliably centering the post via the banjonut, eliminating the need for a stepped peghead bore while removing tilt torque and lateral pressure from the string post and rear fixing screw.
Permanently lubricated with Schaller special grease for maintenance-free service, the M6 135 retains the identical footprint of its predecessor for seamless retrofitting and drop-in replacement on compatible guitars.
