Seems to be a popular configuration. I had a Paf pro in the neck on another guitar, and i really wasn't that impressed. The stock neck
pickup on the 550 seemed like more output. The air-norton is also slightly less output than the paf pro. I have also heard the tonezone is slightly muddy. That would make sense considering the high level of mids and bass rating on the dimarzio site. I want something that has great output and sustain in both the neck and the bridge.
