I don't know, but it's fun to think about. I feel like this should be a known jam. Like, if somebody had this tape and listened to it with any regularity they will know this jam immediately. Anyway, I'd rule out 2.0, Trey's tone is not gritty enough.
I'd say it's something summer 99. For example, everybody loves Camden 99, especially the whammy part nearer to the end. Anyway, I feel that the whammy bending use came to be summer 99. And in this clip, Trey is learning about it, playing with it, getting his kicks with his 'new' toy. Also, to support 99, at about 41 seconds Trey hit's/touches on the infamous 99 re-occuring riff. the jiboo riff. That riff was all over the place that summer.
yeah, sorry about the rant.
