does anyone have any advice for me in picking a new pup for my guitar.i am running into a mark 4..with an usa hamer centaura.for some reason the jb thats in there is just not cutting it for me.humbucking bridge position.i was kind of thinking about a dimarzio.i know this is all limited info but i like general hard rock stuff.i like a real middy sound that you can hear the pick cut through when soloing.any advice?
