Well, I was using info provided on the BKP website and compared them to SD distortion stats.
From experience I can tell that output might be disorienting sometimes.
Currently I have CBomb bridge and Cold Sweat neck. And they are around 16k bridge and 8.3 neck.
Previously in neck position I had Dean DMT Michael Angelo Batio signature pickups which was around 12k. According to the stats, vast difference, tone-wise even that the CS is less output it sounds waaay beeter what Dean DMT. It handles distortion waaaay better as well as clean sounds.
And was using them in the same music, playing the same thing (mostly rock/metal)
So my advise would be if the differences are minimal and slight, don`t bother. If you like the sound and the tone of the BKP (or any other pickup) go for it and don`t bother with 1k or so difference.
Obviously when you compare pickups like 17k to 7k, you`ll see that they differ a lot, but other than that go after the tone than the numbers.
By the way medium-high output BKP pickup would be Juggernaut for example in comparison with Painkiller from the contemporary range.
