Some say it was also a compromise for improving the green mode, which is the one mode that seemed to actually improve with revisions (green sucked on the C & D I had)
I personally wouldn’t choose too often my Rev C for ‘80’s rock vs my vintage Marshall’s, ‘80’s SLO and few others I have. The Rev C is still ultimately a very thick/fat, low mid heavy amp. The descriptions guys give can just be misleading since it’s tighter and more aggressive in the upper frequencies than the revisions after, but it’s not a Marshall or SLO in that regard when AB’ed IME, really not even close, but my personal favorite high gain amp for what I like
