Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 sets a benchmark in guitar tuning technology, featuring a precise 1:18 gear ratio for smooth, accurate, and stable tuning comfort. Engineered with high-precision CNC-machined components and surface finishes, it incorporates a self-locking drive to ensure reliable tuning stability.
Crafted with premium brass string posts carefully fitted into the housing, this tuning machine provides maximum wear resistance. The innovative stepped M6 flanged washer centers the post reliably without requiring stepped peghead drilling, eliminating tilting torque and protecting mounting components.
All enclosed housings are permanently lubricated with Schaller special grease for maintenance-free operation. Designed to match standard installation dimensions, the M6 90 offers seamless retrofitting and replacement for existing instruments.
