Different boards do different things to the sound that's coming through them. An old Neve desk does embellish it in a way that makes it sound sort of bigger or warmer. It doesn't change the performance but it does enhance the way that it sounds.

You know, Nirvana used to start rehearsals with the three of us just jamming. For, like, a half an hour, just noise and freeform crap - and usually it was crap. But sometimes things would come from it, and some songs on Nevermind came from that, and 'Heart Shaped Box' and stuff on 'In Utero' just happened that way.

I had a Super Grover doll growing up. Super Grover was very clumsy, he wasn't very good-looking. But in his own way he'd always save the day.

When I was a teenager, working towards dropping out of high school to starting to tour with bands, I'd drive around in my VW Bug every morning before school, very stoned listening over and over to Zeppelin. This song got to me because it just seemed mystical. There is something about those Celtic tunings that almost sounds Eastern. Somehow it would sweep me up into my own little trance-like state, like Sting with those shamans in the Amazon. But all I had was a bong and a Led Zeppelin cassette.

Being in Nirvana was amazing an experience that will never happen again for me. And I look on them as some of the best and worst times of my life. But we're in this band, the Foo Fighters, making music for the love of music. We all came from bands that had disbanded, and we were drawn to each other because we missed playing - we missed getting in the van, loading our equipment, and watching it break down in the middle of a show. And that feeling hasn't gone away. There's nothing I'd rather do than make music. It's the love of my life.

I think musicians like me are drawn to those older desks, not just because they're legend and lore but also because they do something really specific that is hard to emulate or re-create digitally.

There's a big difference between falling in love with someone and falling in love with someone and getting married. Usually, after you get married, you fall in love with the person even more.
