I can't speak to what it would sound like modded with A2; I assume like any other 9k ish PAF with A2, which is in that ballpark.
However, that isn't what DiMarzio/Steve Blucher intended, which was my point. If you're modding it, all bets are off.
I had a Lollar high wind Imperial that was A2 and around that same DCR and I couldn't stand the thing. Possibly my least favorite pickup ever, it fought pick attack like someone stuck a cap across the output and just sounded, and more importantly, felt, awful.
Odd, because the normal wind A5 Imperials are great in certain applications. The neck version especially has a very complex tone.
I had the same experience with the Custom 5 vs the Custom Custom. Just got done putting in and removing a CC from a guitar. Tried it because I have a nickel covered one in a jazz box, where it sounds fine, sort of Larry Carlton ish, but it seems like the cover took out something I dont like because I found the uncovered version had a squeeky affect on the pick attack I just couldn't stand. Put the C5 back in, which is supposedly the same thing with A5 vs. A2 and it is a major improvement.
I've played other A2 PAFS in normal DCR levels (Gibson '57s, Bustbuckers) that sounded just fine, both covered and uncovered.
So maybe I just don't like what happens when you combine A2 and a lot of turns. The stock VHPAF with A5 is a great PAF though.
