Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets a benchmark in tuning precision and reliability. Engineered with an upgraded 1:18 gear ratio, it delivers velvety smooth operation, enhanced fine-tuning accuracy, and exceptional tuning stability. All structural components are CNC-machined to precise tolerances and surface-finished to ensure consistent, maintenance-free performance.
Crafted with premium brass string posts precision-fitted into the housing, the M6 135 guarantees maximum wear resistance and long-lasting durability. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing mechanical stress on mounting screws and internal gearing.
Featuring the exact installation footprint of its classic predecessor, this tuning machine allows direct drop-in replacement without instrument modification. High-grade Schaller specialized grease permanently lubricates the closed housing, maintaining flawless operation across extended use.
