Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 sets a high standard for closed guitar tuning machines, featuring a precise 1:18 gear ratio that provides exceptionally smooth and accurate tuning stability. High-precision CNC-machined components and surface-finished parts ensure consistent, sensitive adjustment with a self-locking drive mechanism.
Crafted with premium brass string posts precisely fitted into the housing, this machine head offers maximum wear resistance and durability. The innovative stepped M6 flanged washer ensures straightforward installation and reliable post centering without requiring stepped peghead drilling, eliminating tilting moments and reducing strain on mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 90 shares identical mounting dimensions with its predecessor model for direct, seamless replacement on compatible headstocks.
