Re: ExplorerPickups
Yeah, the Pros can be a bit clattery sounding...yet also somehow too bassy at the same time. What you are hearing is basically just the difference between A5 and A2 magnets, as BB2/3 and BB Pro neck/bridge can have about the same number of winds, respectively.
Did you get your BB 2 and 3 pulled from a guitar, or as a Gibson accessory (in a clear plastic Gibson case)? If the former, they are wax potted; if the latter, they are not.
