I've just bought some Rebel Yells and they are incredible. In fact I'm thinking of pulling them out of my Epi already and putting them into something special! There very versatile but it does depend on what you want your guitar to sound like.
Warpigs in an SG. Personally I think Warpigs sound better in big thick Mahogany bodies. If you want to take advantage of that massive bottom end. But they would still sound very evil! :D
