According to a Christies auction, Jimi Hendrix used a 1966 Marshall Super Lead 100 Watt amplifier head in several concerts from 1967 to 1969.

According to the auction, here are some of the details of the amp head: "...Serial No. 7026, with black covering, front with white plastic Marshall logo, plexiglas control panel with six rotary controls, four inputs, two switches and indicator light, with white stencil lettering J.H.EXP. on the top in two places..."

"...this was likely to be one of the first Marshall amps that Hendrix ever owned and could have been one of three Marshall amps purchased by the Jimi Hendrix Experience on 11 October, 1966."

Marshall have used this amp as a template for their production of a limited edition handwired Jimi Hendrix Signature Super 100JH head.

The personal guitar tech of gustavo cerati, Barakus, tells at 5:05 of the video:

"Cuando yo llegué (al final de la gira Cancion animal) usaba los Marshall, uno era el Super Bass y el otro era el Super Lead."

Ace used these amps in the early years of KISS and they can be seen in this picture.

Premier Guitar writes in this article "when money was finally available, Johnny purchased not one but three Marshall 1959 Mark II Super Lead heads and six Marshall 1960B 4x12 straight cabinets."

During a live performance, Keith Urban discusses his use of the Marshall Superlead Guitar Amplifier Head as part of his amp setup, as detailed in the Premier Guitar "Rig Rundown" video at 9:03.

In his Marshal arsenal, Frampton has Marshall Superlead amplifier. This one was modded by Jose Arredondo, with master volume and effects loop included.

Marshall 100-watt amps were mandatory to cut through the often-sludgy sound of that era’s arenas and coliseums, Asheton points out. In time, he crafted a double or triple stack, “Where they take 200-watt heads, and they’d use a 50-watt head as a preamp – so I had the big sound,” he said. “If I may use the overused word – it’s awesome.”

In the Glastonbury 2019 full set video, Lee Kiernan of IDLES can be seen using a Marshall Superlead Guitar Amplifier Head, specifically cross-patched from the low input of channel one to the top input of channel two.

"There's a real clarity with a Superlead," says Justin Hawkins, at 6:00 in this rig rundown video.

By then we were involved with John Sinclair and the White Panthers, and we started to see Marshall amps coming over from England. Cream played them; we knew Jimi Hendrix used them because we had opened for him. So we bought a load of the original 100-watt Super Lead heads. We got six of them and two 200-watt bass heads. They were terrific-sounding amplifiers, but incredibly inconsistent; we blew them up regularly. You might get two or three shows out of them and then they’d go up in smoke. We’d have two sets of Marshalls with us on the road and one set in the shop all the time.

But what we did with this record is, I wanted to use higher wattage amps for more headroom, so I had a Blackstar Artisan 100, and then I also had a 69 Super Lead and I ran those two together, and Boy, All Mighty was that the sound? It was just so good.

At 11:43 in this rig rundown, Dan Hawkins mentions his Marshall Superlead, saying it's the one thing in the set "that remains the same. It stays constant."
