Seems to have been used alot, not sure where you came up with internet folklore.
I think the ratio is way off in how much it was actually used vs how much it is revered by everyone on the internet. The amp was considered a high gain amplifier and while the design at the time was new I’ll give it that, as far high gain tones, I can think of very very VERY few it was used on. 80s hair stuff? Sure, alittle more I guess, but not much.
