Ok I finally got my bridge Aftermath pickup in my guitar. And I have to say i like, possibly love it already. I only tested it at some loud bedroom levels, but it sounds pretty damn good. It's like I took the stock pickups I had and scrubbed it clean in the sink and removed the mucky muddiness and the over-hyped bass. This pickup is tight, punchy and it sounds mean. The Holy Divers that I tried on the other hand I felt were overly compressed and had a mid range hump I wasn't into. The Aftermath sounds more balanced tonally and clear, but it's got balls. Whoever described this as clinical made clinical my new favorite word hahah. I would describe it as defined and accurate, but not clinical because there's nothing sterile about it. This pickup sounds organic and cutting. I can't wait to get this up to band levels and see where it goes.
One note for other guys that might be having issues with the Aftermath tone. Pickup height really changes the character of this PUP, and I mean dramatically. If you back it to far down it gets really thin and shrill. If you put it up too high it becomes really fat, compressed, murky and mushy. But man when you get it just right in between it's amazing. Do some experimenting. I've found most BK pups react to height more then others I've tried.
