Word of advice:
Don't buy pickups to try and get a sound that an artist has. That's not how you play guitar, unless you're going to be in a cover band. I'd take your guitar and spend some more time with your current pickups, try to develop a sound that you like, then upgrade your pickups if you don't like it, and try and get a better tone/sound out of that. There's nothing wrong with learning a few songs by your favorite aritst, but trying to sound exactly like him defeats the purpose the playing guitar... Just listen to the records if that's what you want.
