Like Twinfan, my first response was something along the lines of "Hmm, doesn't seem to sound any different... maybe a bit quieter". I was playing through stock Ibanez INF2 pickups in my RG series. Over time, and with plenty of pickup height playing, I began to work out what makes the Miracle Man pickups tick, and how to get the really brutal tones out of them, retaining a good amount of bite and crunch, and of course all of that tight ceramic goodness!
As it happens, I also play the strings very hard, I wonder if this trait leads to fewer noticeable differences between pickups/guitars?
