I believe that there's a pretty wide berth between the average Recto player and guys like us geeking out on high end gear forums. For example, most guys I know personally that own Rectos do their own thing and don't socialize about gear. I'd suspect by Recto serial numbers alone, since they've made over 60K Rectos by now, that these guys outnumber us forumites as much as 1000:1.
So then, I do believe the average Recto player is trying to emulate the sounds their favorite bands that used them made, just like the average (high gain) Mark player is trying to emulate Metallica sounds. Just purely by the numbers & probabilities.
That being said, I agree that the Rev C is- among the Recto family- THE best tone & feel. However, I see it is a hybrid between a Rev F and a Mark III and not really a traditional "recto" sound. However, it is a holdover from the 80s hard rock / Metal sound and I totally get how & why the Rev G came to be- and it was smart on Mesas part- to quickly adapt to the brand new sounds that quickly took over.
