Back from the golden age of lap steel guitar, Kluson® has revived the 4 per plate tuning machines used on the Fender® Stringmaster®s, 400 pedal steel and many others. These are exact reproductions and will retrofit your original Stringmaster® tuning machine tray. Not only are these tuning machines made in the original nickel finish, they are also available in chrome and gold to match the Kluson® reproduction of the original tray.
