This is a very interesting topic for discussion. I think if a lot of members come together, we can maybe piece together a pretty comprehensive list. Unfortunately, I haven’t played any of the same Bare Knuckles as you, but I’ll add in my thoughts. I’ve played four different bridge humbuckers: Holy Diver, Crawler, Abraxas, and Juggernaut. The Abraxas and Juggernaut belonged to friends. I did the work upgrading a guitar with the Abraxas (posted a review on it recently too). I have played the Abraxas, Crawler, and Holy Diver through my rig, but I only tried the Juggernaut through my friend’s rig (different friend than the one with the Abraxas). Because the voicing is so different, and I never used it through my rig, I can’t accurately compare the Juggernaut to the others (also played it for much less time).
I’d rank the other three HD the hottest by far, then the Crawler, and the Abraxas the lowest output. Despite similar DC resistances, the Abraxas didn’t seem as hot as the Crawler. I wouldn’t have guessed it was 14k based on my experience with it would have guessed lower maybe between 10-12k.
