Fwiw, just played around a bit with Jays IRs. As has been said by others, B isn't worth much, if anything. Weird honky-phase-y things going on all over the place, regardless of the used amp model. Out of A and C I seem to prefer A for the time being, simply because it sounds a bit richer in the low mid area, but maybe at volume (have only been able to try at a volume that wouldn't make the neighbours call the police, but it was fairly loud...) and in a band context, I might prefer C. Noticed the same thing as with Jays Atomic cabs, there's very little low end affairs that need to be taken care of, something I usually have to deal with when creating my live IRs (and no, I'm not talking Fletcher Munson here, just more or less about "general balance"), in other words: These sound very balanced, which is great. Unfortunately, the speaker captured doesn't seem to be too suitable for overdriven amps, but it goes quite well with the Amplifires 65 Clean and certain pedals in front, so this should be pretty suitable for anything in the blues/fusion realm. On a sidenote: I have one IR that I created myself (using anything else but great source capturing and/or scientific methods to modify those source IRs, to put it carefully...) which comes pretty close in terms of playing feel - but it certainly doesn't sound like any authentic cab. In case I find some time, I'll record some bits later on.
