Hello all: I've got Seymour Duncan 59/JB pickups in my guitar. Right now they are open coiled and I want to put covers on them. So... I have a few questions as this is something I've never done before. 1. Will Gibson humbucker covers fit these or do I need to find SD ones somewhere? 2. Are the 59/JB potted pickups? Is there a way I would be able to tell? 3. Are there any special tricks to installing the covers that help fight any feedback that might result in their application? 4. Is there a resource I shoudl be looking at as a step-by-step? Any advice would be greatly appreciated.
