The Beatles – Sgt. Pepper's Lonely Hearts Club Band (Super Deluxe Edition)

Paul McCartney is known for using Rickenbacker 4001 basses during the "Sgt. Pepper's Lonely Hearts Club Band," "The White Album," and "Abbey Road" sessions. He owns two: a custom spray-painted version and a natural finish. This usage is evident in The Beatles' "All You Need Is Love" music video available on Apple Music.

Paul McCartney played a Fender Esquire on the "Sgt. Pepper's Lonely Hearts Club Band" album, notably on the title track and "Good Morning Good Morning," as shown in the photo from Thecanteen.

Paul McCartney is famously associated with the Epiphone Casino, often seen playing it during his time with The Beatles. A user-uploaded photo further highlights this iconic pairing.

it was used in the Sgt Pepper sessions

This is McCartneys personal piano located in his music room in London. He had it painted by pop artists Douglas Binder and Dudley Edwards in 1967. He used it for writing many of the songs on Sgt Peppers.

“I remember the first time I first saw a photo of their painted car in the Sunday Times Magazine and I thought it was really cool. I told them “I’ve got a little piano I’d like you to decorate in that same style”… It became my psychedelic piano which I wrote a lot of songs on, including “Sgt. Pepper’s Lonely Hearts Club Band”, “Fixing A Hole”, and “Hey Jude”. It’s in its rightful place in my music room in London.”

In this photo from Abbey Road studios you can clearly see George Harrison's Vox Conqueror solid state amp and cabinet that he used extensively for its built-in fuzz effect starting with Sgt Pepper. In the background you can see John Lennon plugged into one of the 2 Dual Showman's given to the band by Fender and not George's Vox. Though gear was fluid with th Beatles, George wound up with Paul's blonde Bassman after the band broke up (it was sued for guitar more than for Paul's bass) and the Beatles constantly swapped amps and guitars in the studio.

I'm not sure if there are any quotes from him about the Vox UL730 amplifier which was one of the Vox Hybrid amplifiers made in England of the mid sixties, which George used starting sometime during the Rubber soul album, through Revolver, and Sgt. Pepper. Later the amp was auctioned off by Bonham's auction house where it fetched a pretty sum!!! here is a link to the info

John Lennon and George Harrison both acquired Epiphone Casinos at the end of 1965. The main difference was that Harrison's guitar had a Bigsby tailpiece while Lennon's had a trapeze tailpiece. This became Harrison's main guitar during the band's final tour in 1966, and was used heavily during the recording sessions of Sgt. Pepper the following year. Harrison would strip the finish off the guitar in 1968, at the suggestion of Donovan. Harrison claimed the guitar sounded better as a result of the finish being stripped. “I think that works on a lot of guitars,” he explained. “If you take the paint and varnish off and get the bare wood, it seems to sort of breathe.”

It was originally purchased by Brian Epstein, the Beatles' manager, and given to George Harrison. Its original color was Sonic Blue, and was used extensively on the band's sixth album, Rubber Soul. But first used on Help.it was Georges main guitar in Beatles between 1965 to 1970. In 1967, he painted it into the way it is today. It can be seen in the music video for "I Am the Walrus". It was later used as a slide guitar when George went solo. Georges favourite guitar was the Fender Stratocaster. He wanted one in 1958. Later he was to buy one but the guitarist in Rory Storm and the Hurricanes wook up earlier and bought the guitar. He finally got his Strat in Dec 1964. From 1965 till his death the Stratocaster was his main guitar in the studio, though this one was set up for slide so he used other Strats for normal playing. It was George that convinced Eric Clapton to start using the Stratocaster in 1970. George always wanted his first electric guitar to be a Fender Stratocaster.

Used on the bass drum for Revolver and Sgt. Pepper's Lonely Hearts Club Band, as stated by assistant engineer Geoff Emerick when discussing "Tomorrow Never Knows" for The Complete Beatles Recording Sessions: The Official Story of the Abbey Road Years by Mark Lewisohn.

Another distinctive element of "Tomorrow Never Knows" was Ringo's hypnotic drum sound. “I moved the bass drum microphone much closer to the drum than had been done before,” says Emerick. “There’s an early picture of the Beatles wearing a woollen jumper with four necks. I stuffed that inside the drum to deaden the sound. Then we put the sound through Fairchild 660 valve limiters and compressors. It became the sound of Revolver and Pepper really. Drums had never been heard like that before.” And Ringo's reaction? "He loved it, there's no question of that. They all loved the sounds. It was exactly what they wanted."

Ringo played the final chord in A Day In A Life.

Lennon bought a Sunburst Epiphone Casino with a white pickguard and the standard Epiphone “trapeze” tail in 1965 and used it as his main guitar until his early solo year ('70s). He play it live during the Beatles tour at Japan (1966), he also used it in all Beatles' studio albums since Revolver, and during the Beatles self-titled white album sessions he sanded his Casino and removed the pickguard, this model would result in a variety of reissues known as the Revolution Ephiphone Casino. After Lennon's death, the guitar was kept by Yoko Ono.

In this photo, a young John Lennon can be seen holding and playing a sonic blue Fender Stratocaster. The details that can be discerned are a white pickguard and a rosewood fingerboard.
