I have installed an EMG 81 pick-up in the bridge position on my B.C.Rich KKV.

I know that the EMG's are internally shielded. Would it be of any help to shield the pick-up cavity with copper foil and then solder it to the volume pot?

At high volumes on stage sometimes there is a lot of feedback, even with the noise supressor on, so I'm trying to avoid this feedback in any way.

Thanks a lot !
