The Kluson 3 On A Plate Deluxe Series tuning machines bring back the classic vibe of 1950s electric guitars. With the oval plastic buttons and nickel plating, these Klusons look the part for vintage reissues and custom builds. Under the hood, the improved 15:1 gear ratio provides more torque and tuning stability compared to vintage Klusons. The housing and buttons are period-correct for a variety of mid-20th century production years. With two plates housing three bass-side machines and three treble-side machines, this complete Kluson set has everything you need to rejuvenate your guitar's tuners. The durable nickel plating protects against corrosion while providing bright, gleaming visual appeal.
