Im working on a jaguar bass project and it has roadworn jazz bass pickups it it. When i got it had cream pickup covers on it which looked cool but just dont match with the way im modding it. I ordered 2 new pickup covers in black from amazon and tried to put them on. The problem is the new covers dont line up flush with the magnets for some reason, but they appear to be the exact size as the old cream ones. What gives?
