on my sg i think i have a grounding problem because if i am not touching anything metal i get an unwanted hiss but i if i touch metal it goes away, does anyone know how to fix this??
It's supposed to do that.
Connect a ground wire between the bridge and a pot (or the switch, etc).
^He said the hum goes away when he touches metal, so it's already grounded properly.
so do i have to buy new wire??
It is SUPPOSED to do that. It's fine. It isn't broken.
