Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and comfort with an upgraded 1:18 gear ratio. Designed to set the standard for enclosed tuners, it offers smooth, velvety adjustments and unmatched tuning stability for high-performance instruments.
Crafted with premium CNC-machined components, all brass string posts are fitted directly into the housing for maximum wear resistance. The self-locking drive ensures consistent, delicate, and stable tuning, while Schaller special permanent grease provides lifetime, maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, this tuner allows straightforward mounting without requiring a stepped peghead bore. This design eliminates tilting torque and securely centers the string post to relieve pressure from both the post and rear mounting screws.
