When I had a Pearly Gates neck, there was so many mids, upper mids, and highs, that it reminded me a lot of a bridge pickup. In that guitar, I originally had a Custom Custom bridge, and the two pickups didn't sound that different to me, even thought one was a hot bridge pickup and the other was a varient of a PAF.
The A2Pro sounds like a cross between a 59 and Seth neck. Less bass than the 59, but more than the Seth. Likewise, less mids than the Seth, but more than a 59.
