Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers precise tuning stability and smooth operation with an advanced 1:18 gear ratio. Engineered with precision CNC-machined components and premium brass posts fitted into sealed housings, it offers consistent, wear-free performance for solid or slotted headstock instruments.
Featuring the innovative stepped flanged washer, this tuner aligns the string post through the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and reduces lateral pressure on both the post and the rear mounting screw for enhanced longevity.
Permanently lubricated with specialized Schaller grease, each closed-housing tuner is completely maintenance-free. It serves as a direct, modification-free replacement for classic M6 models while providing exceptional tuning accuracy across various guitar styles.
