I can give you brands, but I don't know where you live, so I can't be that specific.
A Dimarzio breed would be pretty cool, as would a Seymour Duncan Custom Custom. If you're in the UK, bareknuckle or swineshead may be worth checking out (I don't know which models), and GFS if you're in the USA.

That's a lot of booze. Frankly, I'm impressed. You're of a stronger timber than the average man, jimbob! Hail you.

Yes you should go to a doctor, fucking moron. We can't do anything about your hemorrhoid.

The 490R and 498T on the SG are some very good pickups and fairly hot. If by better you mean more powerful Gibson makes a ceramic 500T for the bridge but it is kind of overpriced. Carvin makes some very powerful and affordable M22's you might consider.
