I love this guitar tone. Reminds me a little of CSNY Woodstock. I reached out to the guy who played it for Buddy Miles but he wasn't giving up any info. Doesn't seem like a Strat. I'm guessing from the period a FuzzFace and a wah. Maybe a LesPaul? Tele?
Like shoe said, direct to board. I used to get a very similar tone by plugging into a channel of an old Teac 4 track that I bought from a guy who had it for sale amongst other things on a rug on 2nd Ave between 6th and 7th, the west side of the street on a Sunday night in 1989. Only channel three worked and I used it specifically for the fizzy, narrow tone that I could get out of it. It always reminded me of a sound that Neil Young would conjure up. I used my ESP Telecaster most of the time.
I am lately feeling as if I am everywhere at once though no place in particular.
