Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an advanced 1:18 gear ratio, it enables ultra-fine, smooth tuning adjustments with zero backlash.
Every component is precision CNC-machined and surface-treated, featuring premium brass posts accurately seated in closed housings. Permanently lubricated with Schaller special grease, these tuners operate completely maintenance-free over their entire lifespan.
Equipped with Schaller's innovative stepped flanged washer with a 0.39 in diameter base, the tuner ensures rock-solid post centering without requiring stepped peghead holes. This unique design eliminates tilt torque and relieves mechanical stress from both string posts and mounting screws.
