Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed with high-precision CNC-machined components and premium surface finishing, it ensures consistent, sensitive, and stable tuning through its self-locking drive mechanism.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance. The closed design features permanent Schaller special grease lubrication, making the internal mechanics completely maintenance-free over its entire lifespan.
Featuring the innovative stepped M6 flanged washer, it enables straightforward installation without requiring stepped peghead drilling. This design reliably centers the string post via the banjo bolt, effectively eliminating tilt torque and taking pressure off both the post and mounting screw.
