Omar Rodríguez-López

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.

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.

Omar can be heard detailing his guitar which was a custom model starting at 00:40 in this video. It was based off a Supro "Super" he started playing and recording the first record with Bosnian Rainbows.

"I just play the simple combo amp, you know, the Rockerverb 50 now, works best for me." – Omar Rodríguez-López on the Orange Rockerverb 50.

The video description offered more detail, "Omar Rodriguez-Lopez (The Mars Volta, At The Drive In) gives an in-depth interview about his Orange Rockerverb 50 2X12 Combo, pedal-board, and his newest musical venture, Bosnian Rainbows."

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.

"And then the newest one would be the Slicer, which I picked up last year, right before we started doing the band, and I got that at, I think, Noisebug in Pomona in California, they always have a lot of great pedals, and [it] sort of goes further into like, the things that I was trying to do with the tremolo pedals, you know, but it has these cool harmonic things that happen in it that just don't happen, you know, with tremolos and, again, it's real versatile, and especially the fact that you can tap tempo the whole damn thing, so you can just sort of be changing it up all the time, so it's pretty cool" – Omar Rodríguez-López on the Boss SL-20 Slicer Twin Pedal, 0:55

"And then, for me, another cornerstone is the Digital Delay, the DD-5, had that since I can remember, since it came out... the most common setting for me is the effect all the way up, if you can imagine that, the 3 setting, and then I have the feedback at about 2 o'clock, and the delay time at about 10 o'clock... I could use that for almost anything, so I really love that... I started writing with a delay pedal a lot, just for the simple reason that 'Oh, it sounds like way more notes than I'm actually playing, I sound pretty good right now.'" – Omar Rodríguez-López on the Boss DD-5 Digital Delay Pedal, 1:33
