Actually I was looking at the Paf Pro as my second comibination, one of my favourite guitarists at the moment (Theodore Ziras) uses this setup. No problems with having to clean up because of expressive pickups, at least it will help the ears to correct any previous technique mistakes. My only reason for considering the Air Norton was that it was the recommended setup with the Tone Zone on the DiMarzio website... although the Paf Pro was also metnioned. So which one goes where? Tone Zone at the bridge or neck?
