My understanding of SRV’s tone is that it was primarily derived from his dime-ing his guitar and his amps, and placing a dimed Tubescreamer, with the gain set relatively low, in between. It didn’t really matter which version of the pedal he used at any point in time since he was using it to further boost his signal. And, back in the 80s, there weren’t a whole lot of pedal choices for doing so. The famous/infamous Tubescreamer mid-hump didn’t hurt, but I doubt he cared one way or another about it.
