It sounds like a ground issue maybe check the wiring group for a diagram for a fix.

Make sure piezo is grounded to the Jack at ground terminal and if you are using a volume control it must also be grounded.

I respectfully suggest it might be much more like an ugly buzzing sound than either a hum or feedback?

And 'the sound goes away..' Do you mean only the undesired 'feedback' or 'hum' (or as I suspect buzz?) or do you mean all sound? If all sound output disappears then you are somehow shorting the circuit with your body, if it suddenly works ok when you touch the jack connector then that's a much simpler thing connecting the ground to the strings will enable you to silence unwanted noise by touching those. You can do a bunch of stuff to bridge the ground to somewhere on your body, a bit of metal, wire in the back, in the strap etc etc

The buzz it what goes away, not all of the sound.

Try insulating the disk with electricians tape, cover it front and back
