Hi,
I finally received my custom axe with BKPs and had some time to test so now I'll try to give a little review (Hard to find words...).
About the guitar. It's a Mayones Setius GTM 7 with a Nailbomb in the bridge and a Crawler in the neck. The pickups are set quite close to the strings (compared to all my older guitars).
Ok, first of all, when I got the guitar I was extremely surprised. This guitar has a ton of highs! Let me explain, before I played a Schecter 006 Blackjack, which comes with a set neck and SD JB and 59. The Mayo is a bolt on neck plus BKPs. So even though the woods on both are similar the sound is totally different which I didn't expect to that extent!
On to the Pickups.
Overall, they sound extremely defined, have lots of highs but at the same time are a bit 'tame' (in a good way). Let me explain this, the SDs have some frequencies which are very cutting. This makes them sound a little to cutting and screaming at times.
The BKPs seem to have less of these frequencies, so they come through very articulate and 'nice'. Hope this was understandable?
Crawler neck:
Vintagey, less mids than your PAF, more highs, really, in this guitar it is almost single coilish (what I wanted). For a not-so-hot neck pickups it has surprisingly big 'chug'.
Nailbomb Bridge:
Chugga, chugga. :D
No, honestly you can chug away if you want. It has gain, without getting brainless. Harmonics are easy. But it is extremely balanced!
Don't know how to explain, it doesn't have any frequencies dominating the others. (If I would have to choose pickups again I would probably choose something with more body/mid, and maybe a little less hot, but it is cool and I'm actually still getting used to the NB and it's possibilities).
If you roll the volume back, you understand why they say versatile. It gets exremely clean!!
It's not like, 'if you roll back and don't pick too hard you can get some cleaner tones', NO, it gets CLEAN!
hmmm, actually this cleaness describes it also when cranked... there's the gain and all but it's still actually an extremely clean pickup.
Split:
Both give very nice and usable split sounds. Each is different but nice.
Ok, hope this helped. Right now I'm changing the strings from 9s to pure nickel 10s and then I'll see how it sounds. Should work great though with the BKPs clarity.
If you have any questions go ahead and ask :)
