"He also used a Fender Bassman on about four songs and a Vox AC30 for some clean tracks. Four microphones were used to mic Kurt's speaker cabinet (he would pick which mic he liked best for each song and its signal was sent through the Neve console at Sound City): a Shure SM57, an AKG 414, a Neumann U87, and occasionally a Sennheiser 421. His main effects were the DS-1 Distortion and Small Clone. A ProCo Rat distortion pedal was also used on some songs on the album (6). "

In an article found on Universal Audio's site, producer/engineer Rik Simpson is interviewed on what gear he used to record Coldplay for their Viva La Vida album. When asked about the signal chain for Chris Martin's vocals in the studio, he mentions how Chris Martin really likes the AKG C 414 XL II Condenser Microphone. Rik Simpson says, "I don't use any other outboard gear when recording. It depends--Chris is a big fan of the [AKG] 414, so we use that a fair bit. He does a lot of vocals in the control room these days as well, with the monitors on, so I don't always like using a condenser mic for that. I'll use a dynamic, like a Shure SM-7 or something. We did use some other mikes other than the 414 as well, but the 414 generally seems to capture what he's about. It keeps it very organic, and earthy, and simple."
