I thought about putting these in my Les Paul but I don't need massively high ouput pickups, just something with enough power and better than the stock one, so I have a ceramic nailbomb in mine. Don't know if its the same sort of difference between a Nailbomb and a Warpig, but I have an alnico and a ceramic version of the Nailbomb in 2 Les Pauls. The alnico one is more "looser" and thuddy, whilst the ceramic has a tighter bass and is more trebley to me.
If you watch Lee's rig rundown his gear is a lot different to than it was in the Suicide Season era, I think he was using ESP's with EMG pickups in with Orange amps. Now he's a Marshall JCM800 user with an OD pedal with the Warpig of course. He uses an 80 gauge bottom string as well which is where that chunky sound comes from!
