Yes. Tighter than the duncan. I think that is a characteristic of the A2 magnets. To me it is a nice feel. MCP makes an Angel Dust which is the A5 version I believe. Never tried it.
Probably will be like the Custom 5 vs. the Custom custom. A2 vs A5. Custom 5 is scooped in the mids with more bass and highs. Punchier where the custom custom is more mids.
If your guitar is a little soft on the bottom to begin with or your amp is loose in the bass then the black iron might come across as too spongy. A personal preferance thing I think. Never had a problem with it but my amp it a VHT deliverance and pretty punchy and tight to begin with.
Grindy mids = Black Iron, Super punchy low end= maybe look elsewhere?
I would say med to med hot in output. More than a hot paf style but a little less than a JB, or distortion
