Due to a change in specifications, I'm selling these to someone who wants them. They are currently installed on a Fender Jazzmaster, so they will be sold after removal. I've only used them at home for about three months after purchase, so there is no clouding or dullness on the chrome. The included plastic buttons are also included. KLUSON firebird tuners, which were discontinued in the 1960s to much regret. They reproduce the original 12:1 gear ratio, screw positions, and external dimensions. ■ Guitar Pegs ■ For Firebird Pegs ■ Post diameter 5/16 inch (7.94mm) ■ Chrome
