Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machine combines legendary design with modern engineering, featuring an improved 1:18 gear ratio for exceptionally smooth and precise tuning. High-precision CNC-machined components and surface finishes ensure smooth operation, delicate adjustments, and rock-solid tuning stability.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine delivers exceptional wear resistance and long-lasting performance. An innovative stepped M6 flanged washer centers the post securely through the threaded bushing without requiring stepped headstock holes, eliminating tilting torque and reducing stress on mounting components.
Permanently lubricated with Schaller special grease, all enclosed tuners remain completely maintenance-free. Designed with identical mounting dimensions to its classic predecessor, the M6 90 allows for effortless drop-in upgrades without guitar modifications.
