Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an advanced 1:18 gear ratio. CNC-machined components and a self-locking drive ensure velvet-smooth operation, fine adjustment, and lasting tuning stability.
Equipped with high-grade brass string posts precisely fitted into the housing, this enclosed tuner guarantees wear-free performance. It features permanent lubrication with Schaller special grease, making the entire mechanism completely maintenance-free.
An innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilt torque and unnecessary stress on mounting hardware while matching the identical installation dimensions of original M6 models.
