Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort. Featuring a 1:18 gear ratio, this closed tuner provides precise adjustment and rock-solid tuning stability for electric and acoustic guitars.
Every component is CNC-machined to exacting tolerances, featuring self-locking brass posts and wear-free internal mechanisms. Permanent lubrication with Schaller special grease ensures completely maintenance-free operation over a lifetime of use.
The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped peghead bore, eliminating tilting torque and protecting mounting hardware from string tension.
