I'm not sure if what you're missing is really a modern cut in the neck position
The reasoning is basically this:
It seems that both Tim and Ben were surprised when I said the Crawler neck was too dark as they see it as brighter than the Emerald, which is a pickup I see as brighter than the Crawler. Odd! Then I mentioned that at times the Crawler neck sounded a bit dull and too rounded and it was at that point that Ben mentioned cut. He argued that although the Emerald neck uses an AIV magnet, it is unique in the BKP range because it uses a modern wire with that vintage magnet and that's why it's both hotter and more cutting. This seems reasonable to me and suggests that I don't want anything that is overly vintage; certainly not more vintage than the Emerald anyway (or not by much). This must be why I also liked the Cold Sweat neck when I had one. I'm also guessing this is why he wasn't as enthusiastic on me getting a VHII neck as although it has the AV magnet, it uses a more vintage wire. I'm just not very good at choosing :?
Emerald? I'd have two guitars with exactly the same neck pickup which seems daft but if it's that good, why not?
Rebel Yell? I don't want anything that's brighter than an Emerald or Cold Sweat neck and from what I can gather, a Rebel Yell is.
VHII? This one has me stumped. I think that Ben may have thought I had a problem with 'fat' and 'vintage' but I don't think that's the case. I like the Holydiver and Crawler bridge models and they're both 'fat' and the Crawler certainly has a vintage vibe even in the bridge. I really do think that the real question is does the VHII 'cut'. I like my pickups to have a certain degree of 'cut', 'bite' and 'tightness' (call it what you will) in the low end so that notes stay well defined but that doesn't mean it has to be 'thin' and 'bright'. I was reading darkbluemurder's comments on the VHII neck and he does make it sound like a good match for a Crawler bridge.
Cold Sweat? I already know I like it but as it's more modern I'd probably have to use it in my main guitar with the Holydiver and move the Emerald in with the Crawler.
