He also spoke briefly about the guitar in an interview with Musicradar.

"My favourite guitar right now is this Les Paul SG - you know what I'm talking about?"

The '61?

"Yeah, '61 something like that, such a cool guitar."

That's a very different vibe for you, compared with the usual Strats?

"Yeah, like I said, I've sort of pulled out of the muscular, kinda' atom bomb guitar playing. It's more fun for me now to… like the lead line in Friends Lovers Or Nothing - I take more pride in having composed that than in having recited an Albert King thing on top of another composition."

Carlos played this guitar during the Woodstock gig in August 1969. It featured cherry red finish, brazilian rosewood fingerboard, two P90 single-coil pickups, Grover tuners, ABR-1 Tune-o-matic bridge and a wrap-around stop-tailpiece. The Maestro tremolo (VMA-1 version – often used on cheaper Epiphones) which originally came with the guitar was moved back to make space for the stop-tailpiece. The strings were never attached to it, but for some reason Santana kept it on the guitar – most likely to balance the guitar’s weight, or he just hoped it’ll add more sustain to the sound.

Carlos stopped using this guitar going towards 1970, when a black SG Special with white P90s took it’s place. He allegedly destroyed it because it wouldn’t stay in tune.

In a 1978 photograph from Abalonevintage, Ace Frehley is shown with a 1961-1962 Gibson Les Paul (SG) Standard featuring a Sideways Vibrola, during his time with Kiss.

For playing slide, Duane usually used the 1961 Gibson SG cherry red which he got from Dickey Betts, who played it in the early days of the Allman Brothers.

Derek’s backup SG; he keeps it tuned one whole step down – Drop D. This one has the tremolo tailpiece.

Bob Weir, the guitarist and composer known for his work in bands like The Grateful Dead, Wolf Brothers, Ratdog, and Dead & Co., is confirmed to have used the Gibson Les Paul Standard (1961 SG) with a sideways vibrola. This is evidenced by photographs shared on the Grateful Dead's official website and Facebook pages, dated from 1972 and 1973, where Weir is visibly playing the instrument. Although there is an instance from around 1969 showing Weir alongside Jerry Garcia and Phil Lesh each playing SG-style Gibsons, it wasn't until 1973 that he began using the 1961 Gibson SG Standard more regularly in performances.

In the early days of The Allman Brothers Band, Dickey Betts played a Gibson Les Paul (SG) Standard with a Sideways Vibrola, featuring banjo frets and a cherry finish. This guitar can be seen in the band's performance of "Whipping Post" at Fillmore East on September 23, 1970, as captured in the video by Allman Brothers on MV. Betts eventually passed the guitar to Duane Allman, who used it until his passing. It was then owned by Gerry Groom before being sold to Graham Nash's wife, who gifted it to Nash. The guitar is currently on loan to the Rock and Roll Hall of Fame.
