I have played the juggernaut 7 string set through basswood body/maple neck ibanez. It sounded great. Every pick up is going to sound different in every guitar. Every pick up ordered from BKP will sound different as well-EVEN if it's the same model.
With my experience, I ordered The war pigs for the same guitar. The first time, I couldn't stand them. Very bland and not much top end..I gave them a second try after realizing, they may have been wounded like cr@p. The second pair I received are still in my guitar and are fantastic. Clear, big, tight, versatile and MEAN.

The juggernauts are sick pick ups though. I would definitely get them if I were you. The low mid response sounds and FEELS great. When you can feel that response under your fingertips, you have a quality pick up.
