Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding tuning precision and velvety-smooth operation with its refined 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-finished, and equipped with a self-locking drive mechanism to guarantee uniform and stable tuning.
Crafted with premium brass string posts precision-fitted into the housing, this closed tuner ensures optimal tuning stability and wear-free performance. Permanent lubrication with specialized Schaller grease keeps the internal mechanism completely maintenance-free over its entire lifespan.
Featuring the innovative stepped M6 flanged washer, it eliminates the need for stepped peghead boreholes while reliably centering the post via the banjonut. This design removes tilting torque and relieves mechanical stress from both the post and rear mounting screws for seamless retrofitting and long-term durability.
