Inspired by this thread, I went and fished out an EMG 81/85 set I'd left at my parents when I was up at new year. Put them in an Ibanez SZ4020 that's been having issues finding a good set: such a boomy low end, even with apparently tight, bright pickups. Still need to give it a while to adjust, but first impression is pretty great. Much tighter, but without a harsh high end.
Now considering EMGs for my 7 string, which has been another problem child for me. Currently got Fishman Tosin's and it's a bit on the grating side. Loads of highs and high mids.
Lower them a bunch to get rid of boomy low end.
