Mark Knopfler is confirmed to use a Gibson ES-350T, which he acquired in the mid-1980s from Rudy Pensa. In an interview with Neil McCormick for The Telegraph in 2012, Knopfler reflected on his early musical influences, stating: “I fell in love with songs when I was very, very small. Chuck Berry made a huge impression, where the rhythm of the lyrics is as important as the music, there’s a ricocheting effect.” Furthermore, Knopfler utilized this Gibson ES-350T while producing Willy DeVille's 1987 album Miracle, specifically playing it through a Fender Vibrolux for his solo on DeVille’s cover of Van Morrison's "Could You Would You?" These details are corroborated by the source "Mark Knopfler and his guitars" on Oneverybootleg.nl.

Taylor Swift used a Gibson ES-350 T in her Gorgeous - The Making of a Song video from AT&T/Taylor Swift Now.

This article states, "Chuck Berry’s most iconic guitar would have to be his 1957-ish Gibson ES-350T, which sported the company’s then-new P.A.F. humbuckers and was used to cut most of his Chess recordings (though Berry was also photographed with an earlier P-90 model, which was introduced in 1955)."

In this video for Frettedamericana, Phil can be seen playing a Gibson ES-350T. There is a good shot of the guitar at 1:12.

I just got a guitar that I’m very excited about – it’s the exact guitar that Chuck Berry played in the beginning. It’s a Gibson ES-350T, plain maple colour, but it’s beautiful and Gibson just made me one. Because the sound of the guitar on those first Chuck Berry records is unbeatable. And also the sound that Scotty Moore played on some of those early records with Elvis, too, on those Gibson hollowbody guitars, was really beautiful.

"I'm playing an old, hollowbody Gibson ES-350T. The warm, dense tone is probably due to the strings. I always use thick-gauged D'Addario strings -- typically an .011 set."

"Ok folks now here’s something you don’t see every day. Not only is this a pretty clean example of a 1959 Gibson ES-350T in natural finish but it used to belong to Franny Beecher who was one of the original members of Billy Haley’s Comets!! Yep, that’s right this guitar played its part in early Rock-n-Roll history. Only Franny himself knows how many gigs this was played on.

The current owner told me that he bought it directly from Franny about 2-3 years ago and he got to chat with him at great length about the guitar and his career as a Comet. There are many photos of Franny playing a mid 1950’s Gibson Les Paul “Black Beauty” but after a certain length of time Franny had to give the Les Paul back to Gibson. He then purchased this ES-350T. The guitar is essentially stock except it had some fret work done some years ago and because the fretboard was planed a bit the inlays became very thin. One is actually missing. I am going to again lightly plane the board, install new inlays, re-fret, new bone nut and set it up for some rockin’ fun times! One interesting point is that the fretboard is made of ebony and has the 'widows peak' near the neck pickup along with the 5-ply binding. You usually see this type of fretboard on the fancier Byrdland model. The double parallelogram inlays are usually seen on the ES-350 but only up to the 15th fret. This guitar has the inlays up to the 20th fret which is one fret more than a Byrdland. This inlay scheme is usually found on the 1959 ES-345 model. These few anomalies make this guitar even more unique"
