Hi zeppelin68! if you are chasing that classic jimi page sound, your Ibanez will not make it happend no matter how much you customize it or swap pickups, the reason is the wood of the guitar, whether you believe it or not, the woods have a huge impact on the sound, not only the pickups. what you need is some sort of guitar with a massive mahogany body and a maple top, like the Gibson les paul like he had, Im talking from experience here. forget about epiphone. they are not using the correct woods, exept maybe the higher end models. I recommend you buy a les paul copy that has the correct woods, there are plenty cheap ones out there, the best are the japanese made like Tokai, Burny, Greco, Fernandes, and more, then swap the electronics out cus they are often crap and also makes a big impact on the sound, then put a burstbucker in the bridge.
and wire it the jimi page style. there are plenty of diagrams on the web on how to do this. good luck
