Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine continues the legacy of the original closed-housing tuner standard with precision engineering and modern enhancements. Featuring an upgraded 1:18 gear ratio, it delivers ultra-smooth tuning feel, pinpoint accuracy, and exceptional stability across all string adjustments.
Crafted with premium CNC-machined components and surface-finished parts, each unit includes durable brass posts aligned to prevent wear. The self-locking drive and internal permanent lubrication with Schaller specialty grease guarantee maintenance-free reliability over extended use.
An innovative stepped M6 flanged washer centers the post securely through the headstock without requiring specialized step bores, eliminating tilting torque and reducing strain on the rear mounting screw. Sharing identical mounting dimensions with previous M6 units, it installs effortlessly for seamless upgrades or replacements.
