Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets an industry standard with its refined 1:18 gear ratio, delivering precise, velvety-smooth tuning stability and control. Building upon the iconic enclosed design introduced in 1966, this upgraded version offers exceptional performance and longevity.
Each component is CNC-machined to precise tolerances and finished with care, featuring high-grade brass string posts engineered for maximum durability and wear resistance. The self-locking drive ensures consistent, sensitive adjustments, while lifetime internal lubrication with Schaller special grease guarantees maintenance-free operation.
The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing stress on mounting hardware. These tuners offer seamless drop-in replacement functionality with classic Schaller reliability.
