Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers precision engineering and legendary performance. Featuring an improved 1:18 gear ratio, it ensures precise, velvet-smooth tuning and long-lasting pitch stability. All components are CNC-machined and surface-treated, while the self-locking drive delivers consistent and sensitive adjustment.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring a stepped headstock hole, eliminating tilting torque and reducing stress on mounting components.
With identical installation dimensions to its predecessor, the M6 135 allows direct replacement without instrument modification. Each set includes mounting hardware, flanged washers, and threaded bushings for solid headstock installations.
