I would ask two questions:
1. Do you still have the original neck pickup in place?
2. Did you discuss your guitar with BKP before ordering the pickup?
I suspect - given that it is an Ibanez - that there is some kind of polarity issue going on between the new bridge pickup and the original neck pickup. There is something weird with Ibanez guitars in this respect. I would get in contact with Bare Knuckle via email and tell them what's going on, where you bought the pickup, and send them those photos.
I don't know enough about this issue to be much help but I doubt that a regular C8 magnet is powerful enough to cause this problems. It is more likely to be a polarity issue, as when you turn magnets toward each other and they repulse each other
Hey, Dave, thank you for answer!
1. No, this is set C-bomb+A-Bomb.
2. Yes, I did. I asked support guy, what Olly Steele uses in his guitar cuz I have the same guitar, I was sure it will be work for me aswell. Then I told him about my guitar and he gave some specs for it including reversed neck magnet, "for Ibanez concepcion" - he said. Also I asked for hex screws if it matters.
I hope this problem is solvable, I was looking the "right sound" with a few pairs of pickups, I want to stop and just to play music already

Btw, I asked guys from tech support, they will probably answer tomorrow.
