The Orange OR-120 amplifier can be clearly seen in the background behind Billie Joe Armstrong in the provided image.

In the video for D'You Know What I Mean? You can see Noel's rig throughout. It consists of 2 Orange OR-120s each with 2 Orange 4x12 cabs. Orange includes photos from the video on its History, Maintenance and Legacy of the OR-120 article https://orangeamps.com/articles/the-or120-from-1974-history-legacy-and-maintenance-part-1/

"This Orange OR120 is from the private collection of Billy Corgan.

This was purchased around the time of Siamese Dream, and was used on the Siamese Dream tour and Mellon Collie tours as a boost. Billy would run a fuzz pedal through this head so he could get an extra boost for volume. It was, by all accounts, hellaciously loud. That said, it wasn't used particularly for solos, but rather as an upper overtone. With the gain dimed on his Marshalls, this would be an extra harmonic overtone over the top. Again, that sounds deafeningly loud, and the stuff of most guitar players dreams.

Cosmetically, this cab is in pretty good shape. It has the tape residue (on the left side) and handful of small scuffs you'd expect from a touring amp. The input jacks have a bit of tape stuck above them, and the control plate has a few tiny nicks. There is dirt worn into the tolex, but nothing grotesque. Structurally, it is solid, with no cracks and perfect corners still. The tube complement seems to be all-original still.

Both inputs and all controls work as they should, with clean pots. This amp can be decliciously clean and articulate at low volumes - it doesn't have to be a face-melter. But slowly turning up the volume and hearing the saturation build will make you smile every time. This is a historic, road-tested, insane rock amp for the serious collector or large venue player. This is 120W with adjustable 4, 8, and 16 ohm settings.

The power cable is attached on this amp head."

hey frendz, just want to send a long overdue shout out and thank you’s to @jessupamps for sending me this OR-120 pre amp and @black35guitars & @solodallas for helping me out with their shaffer tower replica. I love using these two in combination on home recording/demoing especially. They’ve really helped with my recovery by bringing life to my guitar tones and they tend to get along really well with my digital recording setup. I’ve even included the @solodallas pedal onto my pedal board for these upcoming live shows.

From the website of Jessup Amps, the creator of the custom amp:

This is the exact circuit found in the Orange or-120 and retains the same tonal characteristics as the original Orange pre amp
