Kluson now introduces the classic look of stamped steel with the metal keystone button. Never before available in this combination from Kluson, the look is similar to the transition tuners used by Gibson during the early 1970s. These tuning machines give you all the same quality Kluson is known for with a metal button to match tuner plating. Comes standard with vintage-sized bushings for the original peghole size of 21/64 in but for those of you wanting to get the retro look and ringing tone of a stamped Kluson tuner, we also have adapter bushings available to make these fit a die-cast sized peghole of 10mm. Please note: If you are retro-fitting a vintage instrument that has been modified or putting this vintage style tuning machine on a modern instrument you may also need to purchase the part MB65LUS "adapter bushings" to convert a larger size peghole to vintage size to allow for proper fit and function. Available in nickel, gold and black finishes.
