It's all a bit of a crap-shoot, any way you approach it. Even if you sat in on a rig that sounded exactly like what you want with someone else playing, it would sound different, simply because of being used by two different players.
As a 'rule of thumb', the bridge pickup should have more output than the mid, which should have more output than the neck. Subtleties like phasing and magnet polarities come into the picture as well. And just to make things worse, you really can't predict the outcome. You have to try it to find out for sure.
Tone-quest is a bitch. :cool:
