Mars Volta's 2011 tour with Soundgarden, he used a Boss DD5 Digital Delay, an MXR Phase 90, an Electro-Harmonix Memory Boy analog delay, a Boss PS-6 Harmonist, a Line 6 M9 Stompbox Modeler, an MXR M133 Micro Amp, an Ibanez WH10V2 wah-wah, an Ibanez TC7 tri-mode chorus, and a Line 6 DL4 delay modeler. During the Mars Volta's final shows and At the Drive-In's reunion tour, Rodriguez-Lopez switched back to a full-sized Ibanez Jetking guitar, although retaining his preferred single-pickup and volume knob configuration and 24" neck scale. In a recent interview with TC Electronic, he is seen using a blue Ibanez Jetking with two full-size humbuckers. Most recently, while performing with Bosnian Rainbows, Rodriguez-Lopez began to use a mid-1960s era left-handed Supro 3/4 scale guitar with a single pickup in the bridge position. Shortly afterwards, he was seen playing a custom Ibanez guitar that closely resembled his Supro. In addition, Rodriguez-Lopez now uses flatwound strings on his guitar. Rodriguez-Lopez's pedalboard for Bosnian Rainbows consisted of a Boss TU-3 Chromatic Tuner, an Empress Superdelay, a Blackout Effects Whetstone analog phaser, a Catalinbread Semaphore tremolo pedal, a Boss DD-5 Digital Delay, an EarthQuaker Devices Rainbow Machine, an Empress Fuzz pedal, a Catalinbread Calisto chorus/vibrato pedal, and a Boss SL-20 slicer. As producer Rodríguez-López is also notable for his recording, producing and songwriting techniques. He has claimed that he is "ignorant of music theory" and that thus he lacks knowledge in writing music in standard notation, claiming that his songwriting "comes from emotion completely". Rodríguez-López claims to write all of the music for his projects, then dictates the performance to the musicians involved. In addition to his producing credits with the Mars Volta and his solo albums, he also produced the only LP from the defunct LA-based band Radio Vago and in 2009, handled the production of a recording titled "Terra Incognita" from actress/singer Juliette Lewis' band The New Romantiques. Omar also produced (as well as contributed bass to) Sin Sin Sin, the debut LP from the band Le Butcherettes, which was released in 2011 on Rodriguez-Lopez Productions.
