Here is a vintage Kluson Double-Line Tuner up for sale. Those who value the utmost quality of every part of their guitars down to the most minute of screws will appreciate the stability and smoothness of this bass-side Kluson Deluxe, especially if it's for a passion project guitar that captures the likeness of vintage guitars; what better to use for a project like that than a tuner that came all the way from the mid-60s? It has some wear, but it's still in very good condition and is looking to find its new home!
