I use a Seymour Duncan Bridge Invader in 2 of my 3 electrics. Heaviest and most tone absorbent I have ever played. You'll know the invader when you see it cos it looks as intimidating as it sounds. Huge a$$ magnets and all black. This baby blew away the active EMG's I had on my Jackson V and completely smoked the stock pickups in any Ibanez I've ever owned.

It's just my opinion of course but the Bridge Invader does have insane sustain and incredible distortions.
