This set of 3 x 3 Faber tuners are in the vintage Kluson Deluxe style but in a modern housing for guitars with 10 mm (3/8") headstock holes. The string posts have a collar to accept a threaded hex bushing common on most modern guitars as opposed to the traditional push in bushing, this means you can easily add great looking vintage tuners to your guitar without the use of conversion bushings. Featuring an upgraded 1:15 tuner ratio for more precise tuning accuracy over the original Kluson Deluxe style with through hole string posts.
