Pretty cool actually. Not a whole lot of bass- just enough, but it's clear because of the lower output, and VERY raw. I nice snarling midrange to it. I still prefer the Custom though.
I had a Gibson 490R in the bridge for awhile, it was pretty decent too. Maybe a bit ice-picky but I like the midrange profile, and it was still pretty smooth.
It will probably sound cool. The clean tone might be a little cleaner.
I have not tried it, but I have put a small ceramic magnet in a DD and that was pretty cool too.
