Hi. Ive already made a couple posts reguarding this, but i'm rehabing an old bass I got from a friend, and I'm completely re-doing the electronics, pickups and all. I'm pretty new to this, so I only kind of know what I'm doing. I think the cavity needs to be sheilded, but I'm not sure, because it's got the same coating as the rest of the bass. I attached a big picture of the cavity, if anyone wants to check it out. Also if it does need to be shielded, how do i go about doing it? Any feedback would be greatly, greatly appreciated.
