- if I am not mistaken, tuners modestly described as "generic" look like Der Jung tunning machines. I have another model of Der Jung on my Picado and mine are frictionless, just a pleasure to operate them. Perhaps the tuners here are also frictionless ?
EDIT: I just checked out at the Der Jung pages. These tuners are having number DJ-102W- E2 and in their description we read:
...The new S4 Post system features an exciting innovation
The shaft's body becomes friction free thanks to a bearing located at the end of the roller's shaft, providing a smooth and accurate tuning with a minimum rotating effort !!!
