Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision, tuning stability, and refined craftsmanship. Engineered with an upgraded 1:18 gear ratio, it ensures exceptionally smooth, fine, and reliable tuning across all playing styles. Every individual component is high-precision CNC-machined and surface-finished to deliver enduring performance and a self-locking mechanism.
Crafted with premium brass string posts precisely fitted into the housing, the M6 135 guarantees maximum wear resistance and steadfast pitch retention. An innovative stepped M6 flanged washer centers the string post securely through the banjonut, eliminating tilt torque and protecting against stress without requiring stepped peghead drilling. All closed tuners come permanently lubricated with Schaller special grease for completely maintenance-free operation.
Designed with identical installation dimensions to its predecessor, the M6 135 allows for seamless, direct replacement on compatible instruments without headstock modification. It is versatile, robust, and engineered to provide professional tuning accuracy and long-lasting durability.
