Omar Rodríguez-López

Used in Bosnian Rainbows on their first tour and their first album. Its a left handed 3/4 scale 60's Supro "super". Omar bought it because of its thick neck and because it his hand naturally falls where the lower notes were, which he was more interested in at at the time.

This Ibanez AX120 was Omar's main guitar during the early years of The Mars Volta and can be seen in many live performance photos.

The ORM-1 guitar is the artist signature guitar for Omar Rodriguez-López which was first introduced in 2008. He has frequently used this guitar live, as such in the photo.

In an Rig Rundown with Omar, he gave some details on the guitar. He says the guitar was made small and simplistic to suit his hand size and standards. He uses 13 gauge, first acquired by accident, and ended up being more comfortable than thinner strings.

Omar Rodríguez-López of The Mars Volta, De Facto, Startled Calf, El Grupo Nuevo De Omar Rodriguez Lopez, and At The Drive-In is seen playing a Vox AC30 Custom Classic Guitar Amp on top of his Marshall cabinet. Omar has used AC30's in the studio since at least the early mars volta days. He uses an AC30 at live shows when an orange is not available.

Omar's primary live amp until 2011. By 2007 he was using 4 on stage. In 2009 he downgraded to just one, and in 2011 he opted for just a single orange combo. Used as his primary overdrive sound for rhythm guitars in the studio. All heads and cabs were painted white in 2007.

During an interview w/ Orange Amplifiers, Omar Rodriguez-Lopez talks about his Empress Super Delay (Vintage Modified model) [@ 6:01]

"Hands down, the best delay pedal that I've used, just because, again, how versatile it is, you know, and it sounds great, you know, it's not completely analog, but it's not an issue, it sounds so great."

During an interview w/ Orange Amplifiers, Omar Rodriguez-Lopez talks about his Electro-Harmonix Holy Grail Nano [@ 6:52]

"I use that 'cause as much as I'd love to use the reverb on the amp, which I was doing for a while, it's a lot to walk back and forth and turn it up and down. For a while I liked that, I liked the challenge of it, you know, but now there's something that I just need to be able to do as quickly and stay over on this side."
