No idea about the Gibson Angus Young.
I have an A5 and an A4 mule, and Riff Raffs.
The DC of the A5 mule is a bit less than the A4.
The A5 mule is a great pickup. Like an A4 with more bite, I'm a big fan of it. The A4 sounds more vintagey though, and has advantages. I made a comparison post about this at some point in the past. The A5 mule has bite, and is a bit more modern sounding when clean. the inbetween position is really nice too, nice quack caused by the A5/4 mix. great dynamics.
edit:
In fact, the guitar you see in my avatar has an A5 mule bridge and an A4 mule neck. I can play ANYTHING with this guitar, and it sounds absolutely excellent.
