Upgrade your guitar's tuning stability with these premium BBSTONE locking tuners. Featuring a vintage-style locking mechanism, these chrome-plated tuners provide excellent string clamping and enhanced tuning precision with a smooth 20:1 gear ratio. The traditional thumbscrew-style locking functionality makes string changes quick and secure, while the rock-solid string posts eliminate unwanted looseness. Perfect for non-locking tremolo guitars and players who love aggressive string bending, these tuners help maintain perfect pitch during intense playing. The innovative two-post height design eliminates the need for string trees, streamlining your headstock setup. This complete set includes 6 inline tuners with all necessary mounting hardware (bushings, washers, and screws) designed to fit 10mm headstock holes. These Korean-made tuners combine classic styling with modern engineering to deliver professional-grade performance and reliability for your instrument.
