Grounding issue? Methinks so

[Agileguy_101]

So I was using my strat at practice the other week and I notice that it's humming more than usual. Like, really loud. I deal with it, but I notice that if I touch the cable, it goes away, and I'm left with the regular amount of noise I'd expect from an SSS strat.

I tried another cable and it still had the issue. I also tried another guitar with my cable and it didn't have the issue. Is something improperly grounded?

Yes.

If you touch the strings or bridge it should go away too. But if only touching the cable fixes it my guess would be a loose jack.

It should get better when you touch the strings, the same way it does now when you touch the plug.

Bad jack. Sometimes you can tighten the "arms" of the jack to make better contact with the plug. Otherwise, you need to replace the jack.
