the miracle man is a bit more scooped in the upper mids, and more low mid/bass heavy than the emg 81
low strings sound quite deep and punchy, and higher strings sound quite trebly, but clear and not harsh
on fast shredding it sounds a lot like an emg when it comes to clarity
the notes really jump and the pinch harmonics sound LOUD
it's a high output pickup, but it won't saturate like most high output dimarzios or seymours
it's cleaner than a duncan custom, duncan distortion and a lot cleaner than a dimarzio x2n for sure
never played the d activator, so I can't compare them
the neck aftermath might be somewhat similar to the liquifire, but I'm guessing by clips and specs only, not experience
