Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series tuning machine sets a benchmark for closed-type tuning mechanisms, engineered with a precise 1:18 gear ratio for exceptionally smooth, accurate, and stable guitar tuning. All internal components are precision CNC-machined, surface-treated, and permanently lubricated with Schaller special grease to deliver completely maintenance-free performance.
Featuring solid brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and long-term wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilt momentum and reducing mechanical stress.
Designed with slightly smaller housing dimensions than earlier iterations, the M6 180 directly replaces legacy units without headstock modification. The self-locking gear drive ensures consistent, delicate tuning adjustments across a wide variety of button configurations and post formats.
