In this Gibson guide how to get the tone of Nuno Bettencourt, it was mentioned that he used more Twin Reverbs.

"Of course, being a rocker in the ’80s and ’90s, Bettencourt had a nice complement of Marshall amps backing him up on stage every night. But Marshall wasn’t the only amp he relied on; he also had some Fender Twin Reverbs for those softer moments."

The amp can be seen mic'd up to the left of Lacy.

Daniel Kessler's touring guitar amp is a Fender Vintage Reissue '65 Twin Reverb Guitar Amp, as seen in this photo of his live rig. He says, "I’ve always liked reverb but with a slightly dirty, almost throwback 60s sound.

Ideally, if I could tour with my old Fender Princeton 60s amp that I use for recording I would, but unfortunately it’s too fragile and not tour sturdy."

Brian's used a pair of Fender Twin Reverbs since at least the early 2000's

They appear to have been refinished in white around the Battle For The Sun tours. He'd used Marshalls before then but it seems to have been just the Twin Reverbs since and he's used his pedals to get his gain sounds.

His rig is stage right in the video.

A picture of Paul Stanley at age sixteen in his childhood bedroom with a red Gibson SG and ‘65 Fender Twin Reverb Amp. In a 1979 Guitar Player interview Paul was asked, “Is it true that you used to use empty speaker cabinets onstage in the old days just to look impressive?”

“Yep.” Paul responded.

“That is part of the show?”

“Yes. When I couldn’t afford a Marshall—I was dead broke—I had a great pre-CBS Fender Twin amp, and I took the brains out of it and built a little cabinet for it, like a Marshall-type cabinet, and I bought two speaker bottoms that were from Holland. They were called Marquis, and they looked very similar to Marshall’s. The only problem was that they were made out of thick, really chintzy fiberboard, and they sounded rotten. It sounded like we were playing through cardboard boxes with speakers in them. But they looked great. We were playing clubs with 80 people, and we had what looked like a wall of amps.”

Dean Fertita uses two fender twin reverb amps when he plays live with The Dead Weather as seen in this video from The Late Show with David Letterman.

In the video "Plugged In: Kenny Beats (S02 E03) | American Professional II Series | Fender" on YouTube, a Fender '65 Twin Reverb amplifier can be seen in the background at the 0:24 mark. This identification is confirmed by an accompanying article on the official Fender website.

T.K. makes heavy use of pedals, but his core setup of a Schecter Telecaster copy run into a blackface Fender Twin Reverb (whether it's a reissue or not is unclear) seems to remain largely unchanged in his various activities. At the Japan Night event in London in July 2015 he used a pair of (apparently identical) Twin Reverbs, though whether this is standard practice in his performances is not apparent since there are not very many photos of him (or Ling tosite sigure) playing live.

At around 1:20 of this video he states that the ‘65 Twin Reverb reissue was the primary clean sound used on the Underclass Hero record and resulting tour by Sum 41.

In the video "Pretty Lights - Tour Bus Studio" on YouTube, Pretty Lights is shown using a Fender '65 Twin Reverb amplifier.

Dave Keuning, guitarist for The Killers, owns a Fender '65 Twin Reverb amplifier, as listed on reverb.com. This iconic amp, renowned for its clean sound and dual 12" speakers, has been a staple across genres like rock, blues, and jazz, making it an essential part of Keuning's gear collection.
