Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 Guitar Tuning Machine features a precise 1:18 gear ratio that ensures ultra-smooth, fine, and reliable tuning. Built with high-precision CNC-machined parts and premium brass string posts, it delivers exceptional tuning stability and long-lasting, wear-free performance.
Equipped with an innovative stepped flanged washer, this tuning machine reliably centers the string post without requiring a stepped peghead hole, effectively eliminating tilting torque and reducing strain on mounting hardware. Sealed with specialized Schaller grease, the internal mechanism remains completely maintenance-free throughout its lifespan.
Designed for easy retrofitting, the M6 180 seamlessly replaces previous M6 models without headstock modifications. Available in a variety of configurations and finishes, it provides musicians with unmatched precision, durability, and tuning comfort.
