Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed to build on the legacy of the original closed-housing benchmark first established in 1966, this upgraded version offers refined engineering while preserving iconic aesthetics.
Every component is precision CNC-machined and surface-finished, featuring a self-locking drive and premium brass posts fitted into the housing for maximum tuning stability and wear resistance. Permanently lubricated with Schaller special grease, these sealed tuners operate smoothly without requiring ongoing maintenance.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch diameter, this tuning machine reliably centers the string post without requiring stepped peghead counterbores. This design eliminates tilting torque and reduces strain on both the string post and rear mounting screw for simple and secure retrofitting.
