Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets an industry standard with an upgraded 1:18 gear ratio that delivers velvet-smooth action and pinpoint tuning accuracy. Every component is CNC-machined and finished for exceptionally stable performance.
Crafted with premium brass string posts precisely fitted into sealed housings, these tuners provide maximum tuning stability, wear resistance, and maintenance-free operation thanks to Schaller special grease lubrication.
An innovative stepped flanged washer centers the string post perfectly over the threaded bushing, eliminating tilting torque and protecting the headstock without requiring stepped drilling.
