Hi everyone, I'm pretty frustrated right now. I just got done putting copper tape on the inside of my Jazz bass to shield it. It got rid of most of the buzz on the neck pickup, but hasn't made really any difference on the bridge pickup. It's a MIM Deluxe (Active) Jazz Bass. I soldered a ground wire going from the tape in the bridge pickup cavity to the tape in the main cavity, and I still can't figure it out. any tips?
