Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high precision and tuning comfort with its improved 1:18 gear ratio. All components are CNC-machined, surface-treated, and driven by a self-locking mechanism that guarantees smooth, sensitive, and stable tuning.
Crafted with premium brass posts fitted into the housing, this enclosed tuner delivers maximum tuning stability and wear-free operation. Permanent lubrication with Schaller special grease ensures completely maintenance-free performance over time.
Featuring the innovative stepped M6 flanged washer, the unit simplifies installation and securely centers the string post via the banjo bolt. This eliminates the need for stepped headstock holes, reducing tilting torque and relieving mechanical pressure from both the post and mounting screw.
