Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machines feature an optimized 1:18 gear ratio that delivers precise and smooth tuning action with exceptional pitch stability. High-precision CNC-machined components and self-locking internal drives ensure velvety rotation and dependable operation.
Equipped with premium brass posts fitted into robust housings, these enclosed tuners provide wear-free longevity. High-grade permanent lubricant within the sealed casing maintains maintenance-free performance across years of playing.
Installation is streamlined through the innovative stepped flanged washer, which centers the post via the banjonut and eliminates headstock tilt torque. Identical mounting footprints allow direct retrofitting without modifying existing guitar headstocks.
