Inside the amp the amp case is already ground, acting as some sheilding from external signals already.


This is why I grounded my shield to the case, so it is at the same ground potential as the case and have the same shielding abilities. The goal was to protect my input wires inside the amp from picking up noise or something like that. I wasn’t worried about external signals... I guess that it’s not what caused my problem since it had no effect on the hum whatsoever.
