I was considering a BKP set for a build I'm ALMOST done with, but I decided to take a chance on a guy in Michigan. Don Smith at Iconix pickups. Seriously great stuff. He did an absolute custom set for me and nailed the tones exactly. When I e-mailed him with what I thought was all the info he needed, he still replied with more questions and asked for links to vids or songs that contained the tones I wanted. Coincidentally, he brought out a set very similar to my custom order(18k instead of 17k everything else the same, double screw poles etc) about a week after he had shipped mine out. He did the set for $110. Yeah. Uh huh. Pennies.
The bridge is only slightly less tight than an EMG 81 and has a really thick character to it. It's not dark, just has a whole lot of meat on the bones but doesn't sound unbalanced. It's hard to describe I guess. Pinches are freakin amazing and palm mutes have authority without getting muddy. The 81 has a plinky character to palm mutes that sits well with metal, but it is kind of *****y. None of that here. Compared to a BKP Miracle Man, it has more mids, is just as tight and is much more open and much less nasal.
The neck is the most perfect neck sound I have ever heard. In my opinion of course. I like a very chimey, but lean neck pup. Something that can do Michael Amott lead tones. What he wound for me exceeded my expectations. I had planned to only put the bridge pup in, but when I heard the neck in a donor guitar it was settled. It has all the characteristics I liked about the BKP Cold Sweat, but it doesn't sound as weak. Tapping on it is heaven that I haven't ever heard before. Sort of a slightly stingy, bell-like tone. It actually made me slow down my melodies so I could hear the attack and the ring of them. It has some compression to the sound, but it's not stifling. It's perfect for me.
And they are silent. No noise issues whatsoever. Quieter than my 81/85 sets. No cool pup covers though. I had to get my own. The BKP Camo finish is just a forced patina on bare nickel anyways. Anyone can do it. Their black covers are spray paint and chip off really really badly. It's a shame to see a well made pup get dressed in crap. They are great pups, even if the price rakes you over the coals.
All of my statements are based on running a drop B guitar through a 5150 and playing metal somewhere between melodic death, folk metal, thrash and just plain heavy riffage like SepticFlesh and Meshuggah.
