Now I have the black nut as far away as possible and the problem with the mono cable is gone. With the stereo cable it still is, but it does less. When I turn the stereo cable, at one point the guitar stops playing. At that point, the red light flashes once. Yesterday I tried a second Parker Stereo ...

Thank you. I'll try different positions of the black nut today. Can you tell if it's the original jack?

Yes, I know that. But the black nut can't be screwed in any more. I'll sand it down this weekend. I don't see any other solution.

Hi,
I have the same problem with my Fly Classic. My output connector is going bad. When I twist the cable, there's a crackling sound.
The problem is that the cable needs to be tucked in a little deeper.
I've tried tightening the outer black nut, but I can't screw any more. It would take 0.5 mm more ...
