Is the case connected to ground? On all of the potentiometers, it can help to ground the front metal piece there also.
Thanks Jensen.
the whole case doesn't seem to be grounded at all.
I'm using a laptop power supply if that at all matters.
What I i did just notice is that when one of my appliances was working i got some hum.

As in white goods? Fridge etc? If so you might try a ferrite core and/or a conditioned trailing socket (if that's the right phrase...).
