Watched it tonight. Series of interview clips from all the legends on the poster and then some, interspersed with show footage from all eras. No narrator voice overdubs and you don’t hear an interviewer asking questions. It’s just all these pros, some with guitar in lap, talking about amps and telling stories. Lots of great visuals of gear.
None of the talk gets too technical, it’s more like a spoken group love letter to tube guitar amplification. There is a bit of dissing on digital, really romanticizing huge stacks, high volume moving air, the smell of glowing tubes yadda yadda. They refer to and show a Kemper a lot but I only heard the word Fractal once.
Speaking as a lifetime guitar freak, I enjoyed it a lot and highly recommend. Cool hearing those guys talk shop and tell stories.
