Just wondering if someone could give me some specific measurements for phase 1 blackout heights to start with in my Ibanez rg 7 string for the bridge and neck pickup. I know it is subjective and varies upon different amp setups but I am just trying to get in the neighborhood for neck and bridge, treble and bass side. I also never know at what point of the pickup it is measured, front, middle or back of the pickup? Mine sit pretty much flat so probably doesn't matter much. This is my first time messing with a seven strings pickup height so that's another reason I am a little unsure. Thanks for any replies in advance.
