Abraxas and 2 Pat Pending 63s. I have high def samples of what these can do in my siggy. Brutal to vintage sweetness in the studio. Live? Vintage up through Metal. In both scenarios, these pickups deliver with authority and there is no sense that they are faking it or are coping the best they can. They deliver the goods. Caveat - not a good choice for drop tuning, however, as the low E can get a bit soggy. Also, the Apache is a great pickup, but doesn't like OD the way the Pat Pend 63 Veneer does.
I don't think the Crawler will struggle with lighter - med gain tones, BTW. I hear classic rock played through Gibson 498Ts all day long around here and they do a respectable job. From what I've come to learn by hearing and reading, the Crawler will pull these tones with authenticity, as well as produce stellar saturated tones.
Coincidentally, I have a HS build that I'm working on and am finally straying from the above referenced pickups for some slightly different juju. I'm going with Crawler and Mother's Milk, but I know I'd be perfectly satisfied with the Abraxas and Pat Pend, Apache, or even the MM single coils. My pref would be with the Pat Pend 63 Veneers having experienced them, with the MM right behind based off of what I've read. The reality of the MM may well exceed my expectations.
