Holydivers aren't "crisp" to my ears, so I'm not it's what you want in the bridge?
Given that it's a Cu24, and you have the option to keep the split coils, I'd get a set of VHIIs.
It's only an SE Custom 24 so it's a straightforward 3-way toggle, though a push/pull is easily installed.
I think my real problem is that I'm torn two ways. I've had a Holydiver before in my Jackson and I really loved it because it was versatile, articulate and thick, with loads of great tone. Don't get me wrong, for what I use the Jackson for, the Miracle Man suits me better but I do miss the Holydiver. However, there's no getting away from the fact that the Holydiver, like my Miracle Man, is a modern pickup that is aimed more at Metal and I want to have a bigger spread of tones between my two guitars and that means I need something that is warm, organic, quite thick sounding, very articulate and with more of a vintage vibe so it's more Blues to very early 80's Metal. From what I can gather, that could well describe the VHII perfectly so it clearly makes sense. Is that an accurate description?
So far so good. The complication arises because with the neck pickup, I'm far more drawn towards the Emerald than the VHII. Listening to the clips, the Emerald is exactly what I want whereas the VHII is just kinda close. What I really need is a pickup for the bridge that is sort of like the VHII (assuming my description of it accurately reflects what it is like) but hot enough to go with an Emerald neck. I've trawled around the website and I can't find a likely candidate. In the contemporary section, the Rebel Yell and Cold Sweat seem too bright and the Crawler is maybe a bit too soft in the bass. In the Vintage Hot section, the Emerald bridge seems too bright as well, the Abraxas is also a bit soft in the bass and the Black Dog's description of 'aggressive' and 'throaty' puts me off, even assuming it was hot enough to live with the Emerald neck.
I'm stumped! MY options seem to be either getting a bridge pickup that suits what I'm after and compromising on the neck or getting the ideal neck pickup for what I want and trying a compromise with the bridge. It looks like I'll be left trying to find the option that is the least compromise but at this stage I just don't know.
