Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 sets the standard for enclosed guitar tuning machines, offering an upgraded 1:18 gear ratio for exceptionally precise, smooth, and effortless tuning. Each component is high-precision CNC-machined and finished to deliver even, sensitive, and stable operation backed by a self-locking drive mechanism.
Built with premium brass string posts carefully fitted to the housing, these tuners ensure superior tuning stability and wear-free longevity. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, eliminating tipping torque, relieving pressure from mounting screws, and removing the need for a stepped peghead bore.
All enclosed units are permanently lubricated with Schaller special grease for completely maintenance-free performance. Designed with identical mounting dimensions to its classic predecessor, the M6 135 drops seamlessly into existing setups without requiring headstock modifications.
