saying that my C-WP equipped guitar is completely different i wasn't talking about the EC... it's a neckthrough made in wenge with ash wings and ebony fretboard!
but yes, i can tell the difference between ebony and rosewood, maybe not much in general tone, but the attack is very different. ebony is very "snappy"...
i love bridge PK in the EC, BUT:
1) you should ask for allen bolts instead of screws, it adds a bit of presence and - from my experience - you should need it.
2) i'm not so enthusiastic about the neck PK. i love it in my ibanez S and in the neckthroug (along with the Cpig), but it doesn't sound dramatically different from the bridge in the EC. don't know why, maybe that's because pickups are very near... even so it sounds very good but i expected something a bit different... if you get allen bolts on bridge pickup and regular screws on neck i think it should work better than my all-screws-set.
to be honest i think they're both excellent choices for both guitars... if you love your EMGs (i didn't liked the 81 and after a while grew tired of the 85 i swapped it with too) you should keep them, but whatever your choice, you could get the other set for the EC in the future... ;)
i haven't got decent bridge painkiller clips, but here's one made with the C-pig+PK. not exactly the kind of things you want it for, but maybe it could help... first solo is the pig (second is a rebel yell), main lead line is played with the neck PK on right channel and neck RY on left channel.
