I'll post DI's tonight.
I like the bridge one a lot. The neck one... mehhh. I prefer the 60 or 81 in the neck. I don't use the neck pos too much, though.
The JH-B is a beefed up 81. A tiny bit more low-end than the 81. More emphasis on low-mids than high-mids compared to the 81, but not as much as the 85. Still more of a cutting, tight, bright, focused kind of sound than other pickups, IMO. A LOT more output than the 81 or 85.
I don't agree with the whole "OmGZ m0ar dynamicz" hype around them. It uses the same preamp as the standard old non-X series, but the coils/magnets/whatever are stronger than the average EMG, so it overdrives their internal preamp a lot more than a standard 81 or 85. If you record DI's, you can see the waveform is a lot less peaky than the 81 and you can hear the preamp clipping a lot more evidently than the 81. I think the only reasons why they'd sound "more passive-like" to me is because the low-end roll-off isn't as extreme as the 81, and MAYBE because the attack is a touch different because of the poles instead of blades, but to me that last thing is pretty subtle, and the higher-output/more distorted thing is not subtle at all. Just my opinion/experience.
