Well, I don't know much about the quality of Ibanez pickups, but I would imagine that oyu will notice a world of difference when you change to a new pickup. As I said, the descriptions on manufacturers' websites should give you an indication of the sorts of pickups you are after. Ask music stroe guys as well about individual pickups that they own, and see if you can find guitars with recommended pickups already installed. They will sound different on every guitar, but you should get a good indication of what they are like. Good luck, and tell us about your choice when you install them!
