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, precise, and effortless tuning accuracy. Each tuner is CNC-machined and finished to exacting standards, engineered with a self-locking drive mechanism that ensures stable and sensitive string adjustment.
Crafted with premium brass string posts precision-fitted into the housing, the M6 135 delivers maximum tuning stability and wear-free performance. The specialized step collar washer reliably centers the post through the banjo bolt without requiring a stepped peghead bore, eliminating tilting forces and reducing mechanical stress.
Permanently lubricated with Schaller special grease for maintenance-free operation, these tuning machines feature identical mounting dimensions to their predecessor model for straightforward, drop-in replacement without instrument modification.
