The guitar sounds on ¡Uno! sound cleaner and punchier than on American Idiot and 21st Century Breakdown.

“I think American Idiot and 21st Century... have that kind of modern, soup’d-up Marshall sound to them. For the new stuff, it’s really stripped down, but I think that cleaner guitar sounds make for bigger sounds, actually. Sometimes, when a guitar gets over-saturated or over- distorted, the sound just gets smaller. But with this, you could just hear the wood of the guitar.”

Did you use your Gibson Les Paul Juniors for the new material?

“I played this old ’65 Double Anniversary Gretsch a lot and I played my Les Paul Juniors. I had a ’59 Les Paul – I was using that a lot for different guitar solos – and I had a Gretsch Brian Setzer Hot Rod, which is excellent, probably the best signature guitar that anyone’s ever made, so I used that for a few solos.

“I’m on the left side of the speaker and Jason White is on the right side of the speaker, and he’d play a lot of Les Paul Juniors and he’d mess around with Silvertones and things like that.”
