You definitely should look into your options in terms of wiring and control systems. You should also be aware that high-output pickups that are designed and built with distortion as a goal do not offer nearly as much tonal versatility as a more 'mainstream' design. To me, EMGs all sound pretty much the same :p , but a good passive single-coil, or better yet, a 4-wire humbucker, can do it all.[/font]
