crawler
Sorry to be an "Ass" asking a bizillion questions lol, but why do you say the Crawler? I've listened to the clips, and the top end seems extremely rounded, which I'm not a fan of over rounding the top end. But yet again it could be amp settings, EQ, or a warm guitar on the clip, so just thought I'd ask @)
The Crawler is indeed rather warm & fat - "rounded" - yet with enough bite to cut thru the mix and a nice low-mid growl. Great singing lead tones FWIW and a truely versatile pickup, much more "polite" than the ABomb but still rocking.
It does match part of your whishlist, at least the "something a little less contemporary, but also not really vintage" and the "more higher output pickup with a Vintage Character" thangs. But yes, you might find it a bit too smooth and compressed, depending on the guitar - mine are on a maple going-thru neck / maple sides / rosewood fretboard 80s japanese Vox, so a very different beast, and one that already sounds a bit "compressed" (going-thru neck effect I think) unplugged. In your own alder strat it will possibly sound brighter and more open, can't tell (but it has been designed to sound good in strats). From what I know of the Abraxas, it should be a bit brigther and less compressed, rawer, and way more vintagey - but still beefy.
Oh and yes: the Crawler bridge is AV, not AIV. The Crawler neck is AFAICT very close to the abraxas, just tweaked to match the hotter and more modern AV bridge.
Hope that helps...
