I wouldn't agree, personally. We all hear things differently, for sure, but I've always found that the less lows (and, consequently, more mids) you have *pre distortion*, always leads to a tighter tone. Exactly why people use tube screamers to tighten up flubby amps.
That being said, though, I have not got a lot of experience with A2 pickups, because I haven't liked any of the few that I've tried. But not because of their EQ curve, but rather, because they tend to be a bit less up-front and bold-feeling than A5.
I've always thought the impression that A2 is loose has to do more with low output, squishy compression, and less immediate feel rather than EQ.
