Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for closed-type tuners, delivering unmatched precision and tuning stability. Engineered with an upgraded 1:18 gear ratio, it ensures an ultra-smooth, fine-tuned, and responsive adjustment process. Every internal component is CNC-machined and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Crafted with premium brass string posts and high-grade housing, this tuner minimizes mechanical wear while ensuring maximum durability. The integrated stepped flanged washer centers the string post precisely through the hollow screw without requiring stepped peghead drilling, effectively eliminating tilting torque and reducing strain on mounting screws.
Designed to easily retrofit older M6 models without headstock modifications, the M6 180 seamlessly fits standard solid and slotted headstocks. Its self-locking drive and robust internal construction provide reliable tuning retention across demanding playing environments.
