I wanted to change the stock pickups on my ibanez s570b which is a mahogany body guitar with a bolt on maple wizard neck with rosewood fretboard. It has a floating bridge.

I play mostly metal. Thrash, Progressive, Djent. I also play some alternative stuff and hard rock stuff. I also indulge in some Pink Floyd, Dire straits type of stuff too.
For the bridge I would like a high aggressive output and a tight lower end. I prefer a great attack and fast response. I do a lot fast riffing. Also a thing to note is that the s series is quite different from other mahogany guitars as it has a very thin body.
For the neck i want i dont know how to put it but a tone that sounds somewhat similar to Joe Satriani and Vai(Think For the love of god, Surfing with the alien, Flying in a blue dream). It needs to have a great fluid singing tone with aggressive output. It needs to have a great sustain and harmonics. I also play some fast shred stuff and sweep picking type stuff. It needs to have nice sparkling cleans too.
I was thinking about Nailbomb or Painkiller in the bridge and Aftermath in the neck.
