I delved further into this and I revisited the exact same settings above today: .999 Pitch A and the 1.000 Pitch B but with the H910 and the H949 emulations and I listened intently to see if there were any differences and to my surprise there were.....
The H910 had more of an intense phase shift swirl to it and it was obvious it had detune going on and the H949 was alot more subtle with less of a noticeable phase swirl going on....I really had to pay attention but the detune was there and I feel the guitar main dry tone shined through a little better with the H949-1 on the Pitchfactor. I think the H949-2 setting is H949 modern selection whatever that it is? I didn't try that one.
I liked them both but the argument that the H949 was used seemed to be supported by what I heard today. You can't go wrong with either depending how you hear it in front of the 4x12 cabinets and what you want to hear but I may be in the H949 camp now.
