Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio for precise and velvety smooth tuning. CNC-machined components with a self-locking drive ensure velvet-like operation, exceptional tuning stability, and completely maintenance-free performance thanks to permanent Schaller special grease lubrication.
Equipped with high-grade brass string posts precisely fitted into the housing, these tuners minimize wear and deliver lasting reliability. The innovative stepped M6 flanged washer reliably centers the string post over the banjo bolt, eliminating the need for step-drilled peghead holes and preventing tilting strain on both the post and rear mounting screws.
Engineered with identical mounting dimensions to its predecessor, the M6 135 serves as a direct drop-in replacement without requiring guitar modifications. Suitable for solid or slotted headstocks across multiple configurations, it pairs timeless design with modern German engineering precision.
