Tyson Ritter

at 0:30 you can see him singing into a shure sm57

this is one of the visible things (it has an external pop filter).

the link takes you to a collection of pictures that show Tyson Ritter playing a jazz bass while performing with The All-American Rejects in South Beach, FL in February of 2010.

Starting at 1:22, Tyson Ritter talks about the Fender Bass guitars he uses: “I was kinda torn whenever I got the Jazz Bass because it played beautifully, but didn't have the beefy bottom that I love on a P Bass. Or I guess the dirty bottom that a P Bass has. It’s got a round clear bottom but… I think every song we play a different bass, it’s not like we record with P Basses the whole time, so I think it just depends on getting as close to the sound that we achieved on the record.”

Around 1:26 into the video you can see a shot of him playing a Fender Precision Bass in what appears to be an Olympic White color.
