EB 2016 2 Band Stingray Classic Problem

Hi Guys…..I wondered if anyone can help me out with a problem I am having with my Stingray. I am thinking that there is a problem with the plug socket. I use a Mogami Gold cable with a straight plug end going into my interface and a angled plug end going into my Bass. I am getting all kinds of distortion and cut outs and also crackles when I move the angled plug end. I tested the battery which was at 9.67v so thats ok, I then plugged it into my Fender Pand J basses and everything was ok. I then reversed the cable plugging the angled end into my interface and the straight end into my Stingray and everything was ok.
So the problem only happens when I plug the angled end of the Mogami cable into my Stingray.
I have another cable which is just a long patch cable with an angled plug at one end and that is ok.
This is really bugging me and would love some feedback on it.

Cheers
Karl.
