Duesenberg MZK6RG Z-Tuners Junior

6 right. Gold. The new Duesenberg Tuners! Like with a slotted tuner the string is just put into the shaft but then pulled all through the machine head to the backside of the headstock. Here it is cut off. Something like 1mm may look out of the housing. Just push it back softly with the tip of your finger and you can start tuning. If you don’t have a cutter you may also thread the string through the additional horizontal hole of the shaft. Genious and simple! Drill hole 10mm.
