Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark for closed-gear tuners, featuring an upgraded 1:18 gear ratio for velvety smooth, high-precision tuning. Each component is CNC-machined and surface-treated, while self-locking drive mechanics ensure lasting pitch stability and minimal backlash.
Crafted with premium wear-free brass string posts precisely fitted to the housing, these tuners deliver long-term reliability. The innovative stepped M6 flanged washer reliably centers the string post via the hollow bolt, eliminating tilting moment and removing the need for a stepped peghead bore.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 shares identical installation dimensions with its predecessor for straightforward drop-in replacement without instrument modifications.
