Ed O'Brien

In this photo, Ed O'Brien can be seen playing through a Super-Sonic 112.

Ed used a pair of Fender Pro Junior IV combos as his main amps for his 2020 solo tour. They were mounted on Fender Small Amp stands. You can see them at 0:20 in the video

In this Fender video interview, Ed O’Brien discusses his Fender Vibro-King combo amp: “I start with the guitar. So I start with a true guitar, one that speaks to me. So it’ll be a Strat probably. And then make sure I’ve got a good amp. So on the last tour, I used Vibro-Kings, and in my humble opinion, it’s the finest big amp out there. I’d had a setup that I hadn’t changed for years and years, since the very beginning, since 1992. I A-B’d it, the Vibro-Kings, with - I had a day in our studio - and to me, I was just like, ‘this is the one.’ And the reason I sort of went for it was because I remember watching Live 8, that was 2005… and Pete Townshend’s guitar sound was just off the scale. To me it was the finest sound there. And I just thought, ‘OK what’s he playing?’ And, 'OK, he’s got a Clapton Strat. And what’s that thing? It’s called a Vibro-King,' I’d never heard of a Vibro-King. I was intrigued, and it works great with my setup, because it’s great if you go straight into it. But also coloring it with effects and stuff like that works great.” (5:43)

Behind Ed, at 0:05 minute mark, there is Fender Twin Reverb.

Throughout the video you can see Ed using the Mesa Boogie Mark V Head.

This photo is taken from Rock Werchter 2017 and shows the amp used by Ed onstage. Ed also added details about the amps in an excerpt from this article:

Lately I’ve been using Audio Kitchen amps - I’ve got two Big Chopper heads and a 1x12 cab: they’re just amazing!

Ed O'Brien is seen using a Mesa/Boogie Mark III Amplifier during Radiohead's performance of "Creep" at the MTV Beach House in 1993, as captured in a video by shreddycap on YouTube. Note: The initial submission mistakenly listed the Mesa/Boogie Mark V Amplifier instead.

To the left of Ed you can see his two Mesa Boogie Trem-O-Verbs. You can also find these amps on "The King Of Gear:"

"Ed has used two of these Mesa Boogie combos since before Pablo Honey. Ed’s two originals, used on Pablo Honey and The Bends, were stolen in 1995, but he quickly purchased two new ones. Those two were used until 2009.

Originally, Ed would set one of the amps to heavy distortion, and the other quite clean, using a Boss LS2 to switch between them. On Creep, he used the a tremolo pedal with the clean amp for the verses, then switched to the tremolo-less distorted amp for the choruses.

Ed currently owns two, “both from 1995-6, they are slightly different but both run with standard Boogie 6L6 / ECC83’s.” Mic’d with a Shure SM57 until circa 2006, then with a Sennheiser 609.

For reference, Ed’s Mesas will be designated as such:

Mesa Boogie Dual Rectifier Trem-O-Verb No1 Clean 1992-1995 Mesa Boogie Dual Rectifier Trem-O-Verb No2 Distortion 1992-1995 Mesa Boogie Dual Rectifier Trem-O-Verb No3 Clean 1995-2009 Mesa Boogie Dual Rectifier Trem-O-Verb No4 Distortion 1995-2009"

Ed O'Brien is confirmed to use a Fender Vintage Reissue 65 Deluxe Reverb 1x1 Tube Combo Guitar Amplifier, as evidenced by an image of his Deluxe Reverb head taken in Tel Aviv on July 19, 2017.

Ed O'Brien can be seen using the Fender Custom Series '57 Bandmaster Tube Hand-Wired Guitar Combo Amplifier while playing his Fender EOB Signature Strat on That Pedal Show, with the amplifier mic'd up behind him as shown in the source image.

In a video by TheGigRig titled "Radioheads New Touring Pedalboards Design, Build and Gig for Ed O'Brien and Colin Greenwood," it is confirmed that Ed O'Brien uses a Lazy J 20 18W 1x12" Combo Amplifier. The video, which provides a behind-the-scenes look at the setup for Radiohead's performances, shows this amplifier being used by O'Brien at the 5:45 mark. The video narrator remarks on the harmony between the Hiwatt and Lazy J amplifiers, stating, "It was beautiful seeing the amps that he was using, the Hiwatt and the Lazy J, the way they complemented each other."
