The Kluson 6-In-Line Deluxe Series tuning machines bring back the iconic look and feel of vintage tuners, now with modern enhancements for rock-solid tuning stability. The Kluson Deluxe Series features oval metal buttons and nickel plating that nail the retro aesthetics. But under the hood, the improved 15:1 gear ratio provides much more accurate and secure tuning than vintage tuners could achieve. The tuners have Kluson's SafeTi string posts to firmly grip each string in tune through heavy playing. The complete set comes with everything you need to install on your guitar, including vintage-style bushings and mounting hardware for a seamless fit and finish.
