I have a Ibanez RG570 w/ a basswood body, maple neck and a rosewood fingerboard (edge tremolo)

I use 12-56 nickel wound strings tuned to DGCFAD.
I mostly play metal but have been playing alot of opeth lately.
this is the sort of tone that i'm pulling out of my current pup (dimarzio d sonic) that i'm moderatly happy with but i have always wanted to try out BKP.

Will the warpig be too dark or muddy in this guitar? (i plan on pulling the string guage down a bit very soon and going back to standard tuning quite possibly, but i dont know how much of adifference this is going to make)
A little dark si fine, i consider opeth's tone to be a little dark, but not over dark.
Oppinions greatly appreciated.
thanks in advance,
Dan
