Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high-precision German engineering, setting standards for sealed tuners. Featuring a refined 1:18 gear ratio, it ensures velvet-smooth and exact tuning accuracy for demanding players. All components are CNC-machined and finished to deliver maximum durability and play-free performance.
Equipped with high-grade brass string posts matched precisely to the housing, the M6 90 delivers exceptional tuning stability and zero wear over time. The innovative stepped M6 flanged collar simplifies installation and reliably centers the post without requiring stepped headstock drilling, eliminating tilt torque and protecting mounting hardware.
Each sealed tuner is permanently lubricated with proprietary Schaller special grease, rendering it entirely maintenance-free throughout its lifespan. Designed with identical mounting dimensions to its classic predecessor, it offers a direct, modification-free upgrade for standard headstocks.
