I hope it's OK to post this here. I came across it by accident and being a Beatles fan from the sixties I found it quite interesting. There are more of them too, which I plan to investigate.
p.s.
Sorry if it's been posted before, it was new to me.
I'd take the amp info portion of that, maybe more, with not only a grain of salt, but perhaps the whole shaker. He does a great disservice by using a silverface Showman/2x15 cab as an example, when all historical records show that Paul employed a blond Bassman/2x12 rig(among other amps). You may think that a Fender is a Fender is a Fender, but it's an entirely different sound. Come early '69, when they shifted over entirely to silverface, Paul used an upright cab Bassman set-up, still featuring dual 12's. They just didn't need 'loud' amps anymore, and in late '66 to early '67, Vox was still their go-to brand(along with a random Fender or Selmer guitar combo). Right at that point in time, they all utilized the short-lived Vox UL hybrid line...transistor pre, tube/valve power. The guitar sounds on that album are certainly unique...sharp, almost shrill. Even with the Vox, Paul employed a 2x12 cab.
If you want to do serious research, beyond Geoff Emerick's book, you'd be better off checking into the unquestionable scholarship of Mark Lewisohn, Jim Elyea, and Andy Babiuk. I'm aquainted with Elyea, I've seen his amp collection(he owns a prop house and supplies period correct music gear to film studios), but his massive volume on Vox amps is a bit hard to come by, and pricey. There's yet another huge, rare, expensive, but intensely detailed book on
everything technical that the Beatles encountered, but the name of it escapes me right now.
