A guitar is just theoretically built wrong. Each string is an interval of fourths, and then the B string is off. Theoretically, that's not right, all the strings should be off.

I mean it's funny, playing music, how of course you want it to do well, you want them to like it, but it's not competitive like an election, it's the Olympics, it's not a Formula 1 race. The Billboard charts are just to show you what people like.

When I was growing up and listening to bands like the Dave Clark Five, the groove was what initially got me going. I really like that funky, heavy groove.

I have selective hearing.

My son, Wolfgang, plays drums, guitars and bass.

The stainless-steel frets were a major breakthrough, because of the amount of playing and bending that I do. I have to get my guitars refretted every couple of months.

I think Clapton is brilliant. He's the only one who moved me. The only one who made me want to play the guitar.
