The Beatles used AC50s on A Hard Day's Night.
Haha! OK, AC50s then!
Ya know, I have the Beatles Recording Sessions Book, and the picture facing the notes on the Hard Days Night sessions has an AC30 on some sort of chair or stand. But, it turns out, that was from two weeks before at a studio in France for something else.
I don't have any pictures from that HDN session, and the session notes don't indicate the amp model.
So I'm wondering where to get that info?
For me 'kraang' is the sound AC/DC gets. That percussive power chord crunch of an old non-master volume Marshall that's right on the brink. Somewhat cleanish, but still crunchy and mean with lot's of bell-like overtones.
