I'd be surprised if the different color models have different pickups - it doesn't really make sense. I have never heard of this before. If they do in fact use different pickups depending on color of guitar, I'd call them "otroligt knäppa i huvudet!".
The humbucker is great on my Blackie! It has really nice edgy sound that isn't over the top. Some buckers can be too gainy and too much output, but this one is great. I will not change it.
