Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed with CNC-machined components and high-grade brass posts, it guarantees exceptional tuning stability, smooth operation, and long-lasting durability.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical stress on both the post and the mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 135 retains the identical mounting dimensions of its classic predecessor, allowing for seamless direct replacement.
