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 smooth, velvety, and ultra-precise tuning. Built upon the legacy of the original 1966 design, this model delivers unmatched tuning stability and refined performance for modern guitarists.
Precision engineered with CNC-machined components and surface finishes, all string posts are made from high-grade brass and fitted seamlessly into the housing. The self-locking drive and permanent Schaller special grease lubrication ensure entirely maintenance-free operation and exceptional durability over time.
Installation is straightforward thanks to identical mounting dimensions to its predecessor and the innovative stepped M6 flanged collar. This collar reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing pressure on mounting screws.
