Installed this set into an Ibanez RG570, got exactly the heavy beef sound I've been looking for! This thing now growls! High output and lots of bass and mids, while retaining clarity. I like to turn up mids and treble on the amp a bit to get a balanced tone. With coil splitting, neck pickup has an interesting straty-kind of tone too. Easy to install, and SD website has tons of wiring diagrams which are easy to find and read (unlike DiMarzio). And they also look killer!
