Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine continues a legendary standard in sealed machine heads, engineered with a 1:18 gear ratio for smooth, velvety, and high-precision tuning. Each component is precision CNC-machined and finished to deliver dependable, slip-free performance and exceptional tuning stability.
Built with solid brass string posts that fit precisely into the housing, the M6 180 minimizes wear and ensures long-lasting reliability. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing, eliminating tilting torque and removing stress from both the post and rear mounting screw without requiring a stepped peghead bore.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. Designed for direct replacement of previous generations without headstock modifications, they offer smooth operation and unmatched durability for any demanding player.
