Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision guitar tuning with an advanced 1:18 gear ratio for smooth, accurate adjustments. Precision CNC-machined components and high-grade brass string posts provide exceptional tuning stability, durability, and wear-free performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring stepped headstock drilling. The self-locking drive and internal permanent lubrication with Schaller special grease ensure long-lasting, maintenance-free operation.
Designed to fit modern and vintage instruments, the housing replaces legacy M6 tuners without headstock modifications. Supplied hardware includes standard mounting screws, threaded bushings, and washers for solid headstock configurations.
