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 ultra-precise, smooth, and dependable tuning. All components are precision CNC-machined and finished to deliver seamless, sensitive, and stable performance with a self-locking drive.
Crafted with premium brass string posts precisely fitted into the housing, this machine head provides maximum tuning stability and wear-free operation. The innovative stepped M6 flanged washer ensures effortless mounting and centered post alignment without requiring stepped headstock drilling, eliminating tilting torque and relieving tension on mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free longevity, the M6 135 shares identical installation dimensions with its predecessor model, allowing seamless drop-in replacement on electric and acoustic guitars without instrument modifications.
