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. Premium CNC-machined components and high-grade brass string posts provide smooth operation, exceptional tuning stability, and wear-free performance.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screw.
Each sealed tuner features permanent Schaller special grease lubrication for entirely maintenance-free reliability. The refined housing offers a seamless direct replacement for legacy M6 models without any headstock modifications.
