Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 features an advanced 1:18 gear ratio that delivers exceptional precision, smooth operation, and reliable tuning stability. Designed with high-precision CNC-machined components and self-locking drive technology, it ensures sensitive and consistent string adjustments.
Crafted with premium brass string posts precisely fitted into durable housings, these enclosed tuners are permanently lubricated with Schaller special grease for completely maintenance-free performance. The innovative stepped M6 flange washer centers the string post securely without requiring stepped headstock drilling, eliminating tilt torque and taking pressure off mounting hardware.
Engineered with identical mounting dimensions to its predecessor, the M6 135 serves as a seamless drop-in replacement without requiring guitar modifications. High-grade materials and meticulous manufacturing guarantee long-lasting durability for discerning musicians.
