Can't beat Bon's humor, lyrics and stage presence…. one of the best imo.
Back to amps seems like angus and malcolm were using their usual 4 input marshalls in this vid. I believe there's a little bit of misinformation floating around lately as people have been saying ac/dc were primarily using 2 input marshalls on highway to hell and back in black. To me if you dial the gain on a 2204 for early-mid ac/dc rhythms, then the solo tone would become thin sounding. If anything they possibly used a 2204 for the powerage album and live 79' let there be rock dvd. Powerage sounds very aggressive compared to previous albums and live 79' ltbr dvd sounded very saturated gain wise.
Btw that vid you posted must be rare one haven't seen it before. Still can't believe ac/dc almost fired Bon in 1975 wtf were they thinking!
